阿尔法拉維ATEX加权系統UltraPure輕芯说明书
The Alfa Laval weighing system is a complete solution offered for process weighing installation,where level measurement,mixing,filling,dosing or batching is required.The weighing solution is as standard delivered in three different accuracy ranges:0.10%,0.05% and0.025%with a total measuring range from0to4000kg.Each weighing system consists of1to4load cells and a weighing module. The weighing modules are available with both analog4-20mA output andfieldbus interface(PROFINET,Profibus DP or EtherNet IP).For high hygienic demands,the Alfa Laval load cells are supplied electropolished and hermetically sealed to IP68(laser welded).Capacitive measurement principle(patented)The Alfa Laval robust digital load cells are based on a patented capacitive measurement principle where a non-contacting capacitive sensor is mounted inside the load cell body.As the capacitive sensor is not in contact with the load cell body,the load cells are to a very high degree unaffected by overloads,sideloads,torsion and welding voltages.Therefore,a straightforward and hygienic mechanical installation of the load cells can be done without expensive and complicated mounting kits and overload protection devices.The electrical installation of the digital load cells is pure plug-and-play as the signal from the non-contacting capacitive sensor is directly converted,compensated and calibrated by a patented ASIC.The digital signal is transmitted as RS485data on a reliable RG-58single wire coaxial cable which may be up to50meters long.The factory calibration of the digital load cells is independent of the load cell cable length.Technical dataStainless steel enclsure..........IP68Stainless steel enclosure with panelmounted display...............IP64Measuring range:..............from0to4000kg dependingon system selection.

Recombinant proteins are expressed as fusions to aC-terminal peptide containing the c-myc epitope and a polyhistidine (6xHis) tag.The vector allows high-level, methanol inducible expression of the gene ofinterest in Pichia, and can be used in any Pichia strain including X33, GS115,SMD1168H, and KM71H. pPICZ contains the following elements:•5′ fragment containing the AOX1 promoter for tightly regulated, methanol-induced expression of the gene of interest (Ellis et al., 1985; Koutz et al., 1989;Tschopp et al., 1987a)•Zeocin™ resistance gene for selection in both E. coli and Pichia (Baron et al.,1992; Drocourt et al., 1990)•C-terminal peptide containing the c-myc epitope and a polyhistidine (6xHis)tag for detection and purification of a recombinant fusion protein (if desired)•Three reading frames to facilitate in-frame cloning with the C-terminalpeptideReference Sources The pPICZ A, B, and C expression vectors may be used with the Original Pichia Expression Kit, and are included in the EasySelect™Pichia Expression Kit (see page v for ordering information). Additional general information about recombinant protein expression in Pichia pastoris is provided in the manuals for the Original Pichia Expression Kit and the EasySelect™Pichia Expression Kit. For more information about the Original Pichia Expression Kit, the EasySelect™Pichia Expression Kit, or their manuals, visit our web site at or contact Technical Support (page 32).More detailed information and protocols dealing with Pichia pastoris may also be found in the following general reference:Higgins, D. R., and Cregg, J. M. (1998) Pichia Protocols. In Methods in Molecular Biology, Vol. 103. (J. M. Walker, ed. Humana Press, Totowa, NJ) (see page v for ordering information).Recommended Pichia Host Strain We recommend using the X-33 Pichia strain as the host for expression of recombinant proteins from pPICZ. Other Pichia strains including GS115, KM71H, and SMD1168H are suitable. The X-33 Pichia strain and other strains are available from Invitrogen (see page v for ordering information). The X-33 Pichia strain has the following genotype and phenotype:Genotype: Wild-typePhenotype: Mut+1Overview, ContinuedExperimental Overview The following table describes the basic steps needed to clone and express your gene of interest in pPICZ.Step Action1 Propagate pPICZ A, B, and C by transformation into a rec A, end A1E. coli strain such as TOP10, DH5 , or JM109.2 Develop a cloning strategy and ligate your gene into one of the pPICZvectors in frame with the C-terminal tag.3 TransformintoE. coli and select transformants on Low Salt LB platescontaining 25 μg/ml Zeocin™.4 Analyze 10–20 transformants by restriction mapping or sequencing toconfirm in-frame fusion of your gene with the C-terminal tag.5 Purify and linearize the recombinant plasmid for transformation intoPichia pastoris.6 TransformyourPichia strain and plate onto YPDS plates containing the appropriate concentration of Zeocin™.7 Select for Zeocin™-resistant transformants.8 Optimize expression of your gene.9 Purify your fusion protein on metal-chelating resin (i.e. ProBond™).Continued on next page2MethodsCloning into pPICZ A, B, and CIntroduction The pPICZ vector is supplied with the multiple cloning site in three readingframes (A, B, and C) to facilitate cloning your gene of interest in frame with theC-terminal peptide containing the c-myc epitope and a polyhistidine (6xHis) tag.Use the diagrams provided on pages 5–7 to help you design a strategy to cloneyour gene of interest in frame with the C-terminal peptide. Generalconsiderations for cloning and transformation are discussed in this section.General Molecular Biology Techniques For assistance with E. coli transformations, restriction enzyme analysis, DNA biochemistry, and plasmid preparation, refer to Molecular Cloning: A Laboratory Manual (Sambrook et al., 1989) or Current Protocols in Molecular Biology (Ausubel et al., 1994).E. coli Strain Many E. coli strains are suitable for the propagation of the pPICZ vectorsincluding TOP10, JM109, and DH5 . We recommend that you propagate thepPICZ vectors in E. coli strains that are recombination deficient (rec A) andendonuclease A deficient (end A).For your convenience, TOP10 E. coli are available as chemically competent orelectrocompetent cells from Invitrogen (page v).Transformation Method You may use any method of choice for transformation. Chemical transformation is the most convenient for many researchers. Electroporation is the most efficient and the method of choice for large plasmids.Maintenance of Plasmids The pPICZ vectors contain the Zeocin™ resistance (Sh ble) gene to allow selection of the plasmid using Zeocin™. To propagate and maintain the pPICZ plasmids, we recommend using the following procedure:e 10 ng of your vector to transform a rec A, end A E. coli strain like TOP10,DH5 , JM109, or equivalent (see above).2.Select transformants on Low Salt LB plates containing 25 μg/ml Zeocin™ (seepage 17 for a recipe).3.Prepare a glycerol stock from each transformant containing plasmid forlong-term storage (see page 8).Continued on next page3Cloning into pPICZ A, B, and C, ContinuedGeneral Considerations The following are some general points to consider when using pPICZ to express your gene of interest in Pichia:•The codon usage in Pichia is believed to be similar to Saccharomyces cerevisiae.•Many Saccharomyces genes have proven to be functional in Pichia.•The premature termination of transcripts because of "AT rich regions" has been observed in Pichia and other eukaryotic systems (Henikoff & Cohen, 1984; Irniger et al., 1991; Scorer et al., 1993; Zaret & Sherman, 1984). If you have problems expressing your gene, check for premature termination by northern analysis and check your sequence for AT rich regions. It may be necessary to change the sequence in order to express your gene (Scorer et al., 1993).•The native 5´ end of the AOX1 mRNA is noted in the diagram for each multiple cloning site. This information is needed to calculate the size of the expressed mRNA of the gene of interest if you need to analyze mRNA for any reason.Cloning Considerations For proper initiation of translation, your insert should contain an initiation ATG codon as part of a yeast consensus sequence (Romanos et al., 1992). An example of a yeast consensus sequence is provided below. The ATG initiation codon is shown underlined.(G/A)NNATG GTo express your gene as a recombinant fusion protein, you must clone your gene in frame with the C-terminal peptide containing the c-myc epitope and the polyhistidine tag. The vector is supplied in three reading frames to facilitate cloning. Refer to the diagrams on pages 5–7 to develop a cloning strategy.If you wish to express your protein without the C-terminal peptide, be sure to include a stop codon.Construction of Multimeric Plasmids pPICZ A, B, and C contain unique Bgl II and Bam H I sites to allow construction of plasmids containing multiple copies of your gene. For information on how to construct multimers, refer to pages 24–31.Continued on next page4Multiple CloningSite of pPICZ A Below is the multiple cloning site for pPICZ A.

Note that there is no blue/white screening for the presence of insert with pPICZ A, B, or C. Once you have obtained Zeocin™-resistant colonies, pick 10 transformants and screen for the presence and orientation of your insert.Important To facilitate selection of Zeocin™-resistant E. coli, the salt concentration of the medium must remain low (<90 mM) and the pH must be 7.5. Prepare Low Salt LB broth and plates using the recipe in the Appendix, page 17.Failure to lower the salt content of your LB medium will result in non-selection due to inhibition of the drug.C We recommend that you sequence your construct to confirm that your gene is in the correct orientation for expression and cloned in frame with the C-terminal peptide (if desired). Refer to the diagrams on pages 5–7 for the sequences and location of the priming sites.Preparing a Glycerol Stock Once you have identified the correct clone, be sure to purify the colony and make a glycerol stock for long-term storage. It is also a good idea to keep a DNA stock of your plasmid at –20°C.1.Streak the original colony out on an Low Salt LB plate containing 25 μg/mlZeocin™. Incubate the plate at 37°C overnight.2.Isolate a single colony and inoculate into 1–2 ml of Low Salt LB containing25 μg/ml Zeocin™.3.Grow the culture to mid-log phase (OD600 = 0.5–0.7).4.Mix 0.85 ml of culture with 0.15 ml of sterile glycerol and transfer to acryovial.5.Store at –80°C.Plasmid Preparation Once you have cloned and sequenced your insert, generate enough plasmid DNA to transform Pichia (5–10 μg of each plasmid per transformation). We recommend isolating plasmid DNA using the PureLink™ Quick Plasmid Miniprep Kit or the PureLink™ HiPure Plasmid Midiprep Kit (page v), or CsCl gradient centrifugation.Once you have purified plasmid DNA, proceed to Pichia Transformation, next page.Pichia TransformationIntroduction You should now have your gene cloned into one of the pPICZ vectors. Yourconstruct should be correctly fused to the C-terminal peptide (if desired). Thissection provides general guidelines to prepare plasmid DNA, transform yourPichia strain, and select for Zeocin™-resistant clones.Zeocin™ Selection We generally use 100 μg/ml Zeocin™ to select for transformants when using the X-33 Pichia strain. If you are transforming your pPICZ construct into anotherPichia strain, note that selection conditions may vary. We recommendperforming a dose response curve to determine the appropriate concentration ofZeocin™ to use for selection of transformants in your strain.Method of Transformation We do not recommend spheroplasting for transformation of Pichia with plasmids containing the Zeocin™ resistance marker. Spheroplasting involves removal of the cell wall to allow DNA to enter the cell. Cells must first regenerate the cell wall before they are able to express the Zeocin™ resistance gene. For this reason, plating spheroplasts directly onto selective medium containing Zeocin™ does not yield any transformants.We recommend electroporation for transformation of Pichia with pPICZ A, B, or C. Electroporation yields 103 to 104 transformants per μg of linearized DNA and does not destroy the cell wall of Pichia. If you do not have access to an electroporation device, use the LiCl protocol on page 23 or the Pichia EasyComp™Transformation Kit available from Invitrogen (see below).PichiaEasyComp™Transformation Kit If you wish to perform chemical transformation of your Pichia strain with pPICZ A, B, or C, the Pichia EasyComp™ Transformation Kit is available from Invitrogen (see page v for ordering information). The Pichia EasyComp™ Transformation Kit provides reagents to prepare 6 preparations of competent cells. Each preparation will yield enough competent cells for 20 transformations. Competent cells may be used immediately or frozen and stored for future use. For more information, visit our web site at or contact Technical Support (page 32).Important Since pPICZ does not contain the HIS4 gene, integration can only occur at the AOX1 locus. Vector linearized within the 5´ AOX1 region will integrate by gene insertion into the host 5´ AOX1 region. Therefore, the Pichia host that you use will determine whether the recombinant strain is able to metabolize methanol (Mut+) or not (Mut S). To generate a Mut+ recombinant strain, you must use a Pichia host that contains the native AOX1 gene (e.g. X-33, GS115, SMD1168H). If you wish to generate a Mut S recombinant strain, then use a Pichia host that has a disrupted AOX1 gene (i.e. KM71H).Continued on next pageHis4 Host Strains Host strains containing the his4 allele (e.g. GS115) and transformed with thepPICZ vectors require histidine when grown in minimal media. Add histidine toa final concentration of 0.004% to ensure growth of your transformants.The pPICZ vectors do not contain a yeast origin of replication. Transformantscan only be isolated if recombination occurs between the plasmid and the Pichiagenome.Materials Needed You will need the following items:Note: Inclusion of sorbitol in YPD plates stabilizes electroporated cells as they appear tobe somewhat osmotically sensitive.•5–10 μg pure pPICZ containing your insert•YPD Medium•50 ml conical polypropylene tubes• 1 liter cold (4°C) sterile water (place on ice the day of the experiment)•25 ml cold (4°C) sterile 1 M sorbitol (place on ice the day of the experiment)•30°C incubator•Electroporation device and 0.2 cm cuvettes•YPDS plates containing the appropriate concentration of Zeocin™ (seepage 18 for recipe)Linearizing YourpPICZ ConstructTo promote integration, we recommend that you linearize your pPICZ constructwithin the 5′ AOX1 region. The table below lists unique sites that may be used tolinearize pPICZ prior to transformation. Other restriction sites are possible.Note that for the enzymes listed below, the cleavage site is the same for versionsA, B, and C of pPICZ. Be sure that your insert does not contain the restriction siteyou wish to use to linearize your vector.Enzyme Restriction Site (bp) SupplierSac I 209 ManyPme I 414 New England BiolabsBst X I 707 ManyRestriction Digest 1.Digest ~5–10 μg of plasmid DNA with one of the enzymes listed above.2.Check a small aliquot of your digest by agarose gel electrophoresis forcomplete linearization.3.If the vector is completely linearized, heat inactivate or add EDTA to stopthe reaction, phenol/chloroform extract once, and ethanol precipitate using1/10 volume 3 M sodium acetate and 2.5 volumes of 100% ethanol.4.Centrifuge the solution to pellet the DNA, wash the pellet with 80% ethanol,air-dry, and resuspend in 10 μl sterile, deionized water. Use immediately orstore at –20°C.Continued on next pagePreparation of Pichia for Electroporation Follow the procedure below to prepare your Pichia pastoris strain for electroporation.1. Grow 5 ml of your Pichia pastoris strain in YPD in a 50 ml conical tube at30°C overnight.2. Inoculate 500 ml of fresh medium in a 2 liter flask with 0.1–0.5 ml of theovernight culture. Grow overnight again to an OD600 = 1.3–1.5.3. Centrifuge the cells at 1500 × g for 5 minutes at 4°C. Resuspend the pelletwith 500 ml of ice-cold (0–4°C), sterile water.4. Centrifuge the cells as in Step 3, then resuspend the pellet with 250 ml ofice-cold (0–4°C), sterile water.5. Centrifuge the cells as in Step 3, then resuspend the pellet in 20 ml of ice-cold (0–4°C) 1 M sorbitol.6. Centrifuge the cells as in Step 3, then resuspend the pellet in 1 ml of ice-cold(0–4°C) 1 M sorbitol for a final volume of approximately 1.5 ml. Keep the cells on ice and use that day. Do not store cells.Transformation by Electroporation 1.Mix 80 μl of the cells from Step 6 (above) with 5–10 μg of linearized pPICZDNA (in 5–10 μl sterile water) and transfer them to an ice-cold (0–4°C)0.2 cm electroporation cuvette.2.Incubate the cuvette with the cells on ice for 5 minutes.3.Pulse the cells according to the parameters for yeast (Saccharomycescerevisiae) as suggested by the manufacturer of the specific electroporation device being used.4.Immediately add 1 ml of ice-cold 1 M sorbitol to the cuvette. Transfer thecuvette contents to a sterile 15 ml tube.5.Let the tube incubate at 30°C without shaking for 1 to 2 hours.6.Spread 50-200 μl each on separate, labeled YPDS plates containing theappropriate concentration of Zeocin™.7.Incubate plates for 2–3 days at 30°C until colonies form.8.Pick 10–20 colonies and purify (streak for single colonies) on fresh YPD orYPDS plates containing the appropriate concentration of Zeocin™.Continued on next pageGenerally, several hundred Zeocin™-resistant colonies are generated using theprotocol on the previous page. If more colonies are needed, the protocol may bemodified as described below. Note that you will need ~20, 150 mm plates withYPDS agar containing the appropriate concentration of Zeocin™.1. Set up two transformations per construct and follow Steps 1 through 5 ofthe Transformation by Electroporation protocol, page 11.2. After 1 hour in 1 M sorbitol at 30°C (Step 5, previous page), add 1 ml YPDmedium to each tube.3. Shake (~200 rpm) the cultures at 30°C.4. After 1 hour, take one of the tubes and plate out all of the cells by spreading200 μl on 150 mm plates containing the appropriate concentration ofZeocin™.5. Optional: Continue incubating the other culture for three more hours (for atotal of four hours) and then plate out all of the cells by spreading 200 μl on150 mm plates containing the appropriate concentration of Zeocin™.6. Incubate plates for 2–4 days at 30°C until colonies form.Mut Phenotype If you used a Pichia strain containing a native AOX1 gene (e.g. X-33, GS115,SMD1168H) as the host for your pPICZ construct, your Zeocin™-resistanttransformants will be Mut+. If you used a strain containing a deletion in theAOX1 gene (e.g. KM71H), your transformants will be Mut S.If you wish to verify the Mut phenotype of your Zeocin™-resistant transformants,you may refer to the general guidelines provided in the EasySelect™PichiaExpression Kit manual or the Original Pichia Expression Kit manual or topublished reference sources (Higgins & Cregg, 1998).You are now ready to test your transformants for expression of your gene ofinterest.

毕赤酵母表达系统使用心得
毕⾚酵母表达系统使⽤⼼得Pichia酵母表达系统使⽤⼼得甲醇酵母表达系统有不少优点，其中以Invitrogen公司的Pichia酵母表达系统最为⼈熟知，并⼴泛应⽤于外源蛋⽩的表达。
虽然说酵母表达操作简单表达量⾼，但是在实际操作中，并不是每个外源基因都能顺利得到⾼表达的。
不少⼈在操作中会遇到这样那样的问题，收集了部分⽤户在使⽤EasySelect Pichia Expression System这个被誉为最简单的毕⾚酵母表达的经典试剂盒过程中的⼼得体会。
其中Xiang Yang是来⾃美国乔治城⼤学（Georgetown University）Lombardi癌症中⼼（Lombardi Cancer Center），部分⽤户来⾃国内。
+ 表⽰优胜于；- 表⽰不如；= 表⽰差不多EasySelect Pichia Expression System产品性能：优点——使⽤简单，表达量⾼，His-tag便于纯化缺点——酵母表达蛋⽩有时会出现蛋⽩切割问题全⾯产品报告及⼼得体会：巴斯德毕⾚酵母（Pichia pastoris ）是⼀种能⾼效表达重组蛋⽩的酵母品种，⼀⽅⾯由于其是属于真核⽣物，因此表达出来的蛋⽩可以进⾏糖基化修饰，另⼀⽅⾯毕⾚酵母⽣长速度快，可以将表达的蛋⽩分泌到培养基中，⽅便蛋⽩纯化。
毕⾚酵母表达载体pPICZ 在多克隆位点（MCR ）3'端带有his-tag 和c-myc epitopes ，这些tag 有利于常规检测和纯化，⽽且在MCR5'端引⼊了alpha factor （α-factor ）⽤以增加表达，并且在表达后α-factor 可以⾃动被切除。
在进⾏克隆的时候，如果你选择的是EcoRI ，那么只需在⽬标蛋⽩中增加两个氨基酸序列即可完成。
另外pPICZ 系列选⽤的是Zeocin 抗⽣素作为筛选标记，⽽诱导表达的载体需要甲醇——甲醇⽐⼀般⽤于⼤肠杆菌表达诱导使⽤的IPTG 便宜。
