This article discusses the inadequacy of 5 vegetable oils as substitutes, as well as the characteristics of 22 D-limonene-based substitutes, all less effective in their chemical role, some capable of inducing health problems, and costing more than twice as much as xylene. Some of the 35 alkane-based substitutes discussed are effective for tissue processing, less toxic, with a cost about the same as xylene, but are not very effective for dewaxing and other staining tasks. Isopropanol (2-propanol) alone or mixed with molten paraffin is a technically acceptable and cost-effective substitute for xylene for tissue processing, but in this study, we demonstrate that the best clearing agents from the sectioning quality and diagnostic value point of view, with automated or manual protocols, are mixturesof 5:1 and 2:1 isopropanol and mineral oil, followed by undiluted mineral oil, all at 50 degrees C, making thema safer and cheaper substitute than xylene. Using a1.7% dishwasher soap aqueous solution at 90 degreesC to dewax before staining and oven drying the stained sections before coverslipping will eliminate xylene from the staining tasks. Tissue processors retorts and conduits can be dewaxed with a 2% solution of a strong glassware laboratory detergent. These 4 methodologies will make the histology laboratory xylene-free but, due to the natural resistance to change, many histotechs will be reluctantto adopt them if they think that their technical expertise could be jeopardized, and the only way these changes will succeed is if the pathologists, as stewards of the histologylaboratory, commit to their implementation.Go Greener Histology & HematologySigma-Aldrich® is Committed to Bringing Safer Greener Alternatives to Our Customers.• Novec fluids are non-flammable, low toxicity fluidsfor freezing histology samples.• Xylene Substitute is non-toxic version of xylenewhich is compatible with all tissue• Formalin Free Tissue Fixatives is a less toxicalternative to formalin. It is also compatible witha number of applications like PCR, IHC and in-situhybridization• HistoChoice® Clearing Agent is suitable as analternative to toluene and xylene for dewaxing paraffintissue sections• HistoChoice Tissue Fixative is designed for molecularbiology and used for in-situ hybridizationThe life science business of Merck operates asMilliporeSigma in the U.S. and Canada.Formalin Free Tissue FixativesM E Boon and L P KokBiotechnic and Histochemistry, 83(6), 261-277 (2008)The German, F. Blum, introduced formalin as a fixative in 1893. Formalin rapidly became popular for hardening and preserving gross human and animal specimens. As a result, microscopy for diagnostic pathology by combining paraffin embedding and formalin fixation was developed. Alcohol-based fixatives have coagulation of proteins as their main preservative effect. Because there is no cross-linking, immunostaining is not compromised, and DNA and RNA is not damaged. Ethyl alcohol was used by Dutch scientists of the 18th century, but was replaced by the cheaper formalin. Addition of low molecular weight polyethylene glycol (PEG) optimized the coagulant fixative, Kryofix. The polyethylene glycol prevents excessive hardening and enhances the speed of coagulation of proteins. Kryofix was used on a large scale for skin biopsies in Leiden between 1987 and 2001. DNA preservation by the formulated coagulant fixative, BoonFix, is related to the concentration of ethyl alcohol, PEG and acetic acid. BoonFix has been used since 2004 in Leiden for over 40,000 diagnostic skin biopsies and more than 100,000 cervical samples.A literature review and three decades of experience with coagulant, formalin-free fixatives in pathology suggest that when health authorities realizethat formalin invalidates expensive tests, it might eventually be eliminated legislatively from diagnostic pathology. Finally, coagulant fixation is optimal for microwave histoprocessing where ethyl alcohol is followed by isopropanol. HistoChoice® Clearing Agent1. I mmunogenicity and contraceptive potential of three infertility-relevant zona pellucida 2 epitopes in the marsupial brushtail possum (Trichosurus vulpecula).Janine A Duckworth et. alReproduction, 133 (1), 177-186 (2007)In a previous study, three infertility-relevant epitopes of possum ZP2 (Pep12 (amino acids 111-125), Pep31 (amino acids 301-315), and Pep44 (amino acids 431-445)) were identified using sera from possums (Trichosurus vulpecula) immunized with recombinant possum zona pellucida 2 (ZP2) constructs, and a synthetic peptide library of possum ZP2 protein. In this study, the three peptides were conjugated to keyhole limpet hemocyanin and 300 mug of each conjugated peptide were administered subcutaneously to female possums (n = 20 per peptide) in complete Freund's adjuvant. Immunogen doses were repeated 3 and 6 weeks later using incomplete Freund's adjuvant. Control animals were immunized with either phosphate-buffered saline only (n = 10) or 300 mug keyhole limpet hemocyanin (n= 10), administered with the same adjuvants. Serum antibodies from animals immunized against these three epitopes bound to the corresponding possum ZP2 peptides, recombinant possum ZP2 protein constructs, and native zona. Possum fertility was assessed following superovulation and artificial insemination. Peptides Pep12 and Pep31 had no significant effects on fertility parameters (P > 0.05). However, animals immunized with Pep44 had lower egg fertilization rates (immunized 19.5% versus control 60.5%,P < 0.05) and produced significantly fewer embryos than control animals (immunized 0.5 embryos versus control 2.4 embryos, P < 0.05). The number of Pep44-immunized females that produced embryos was reduced by 64%. Identification and characterization of possum infertility-relevant epitopes on possum ZP2 protein will assist development of safe, humane, and possum-specific immunocontraceptive vaccines for controlling the introduced possums in New Zealand.2. A simplified method for combined immunohistochemistry andin-situ hybridization in fresh-frozen, cryocut mouse brain sections. Sathyanesan Samuel Newton et. alBrain Research Protocols, 9 (3), 214-219 (2002)A method is described to perform combined immunohistochemistry and in situ hybridization in mouse brain sections. The protocol is specific to sections mounted on glass slides. In contrast to earlier methods that require either paraffin embedding or perfusion ofthe brain with paraformaldehyde, this protocol can be carriedout on fresh-frozen, cryostat cut post-fixed sections. This simple and concise protocol increases the applicability of the techniqueas the RNAse-free immunodetection of antigen is useful by itself for immunologically identifying specific cells of interest and then examining gene expression in those cells using techniques such as real-time PCR and microarray analysis. The use of fresh-frozen, cryocut sections enables reliable detection of easily perturbable post-translational modifications such as phosphorylation and improves the quality of results obtained in subsequent in situ hybridization by reducing the background signal and interference from lower cell layers. Inducible transgenic mice that express either a dominant negative mutant form of the cAMP response element binding protein (mCREB) or CREB, in discrete brain regions, were used in this study. The combined immunohistochemistry and in situ hybridization protocol was used to examine colocalization of enkephalin or dynorphin mRNA, both downstream targets of CREB-mediated gene expression, in cells expressing transgenic mCREB or CREB. HistoChoice Tissue FixativeJ Melrose et. alBiotechnic and Histochemistry, 83(1), 47-53 (2008) Histochoice is a proprietary nontoxic, non-cross-linking fixative designedby the manufacturer to replace formaldehyde based fixation protocols. We compared Histochoice and formalin fixation for several cartilaginous tissues including, articular and growth plate cartilage, meniscus and intervertebral disc. The tissues were stained with general histology stains including toluidine blue for tissue proteoglycans, picrosirius red to evaluate collagenous organization, and hematoxylin and eosin to assess cell morphology. The chondroitin sulfate and heparin sulfate substituted proteoglycans aggrecan and perlecan were also immunolocalized in some of the tissues to provide a comparison. Histochoice did not fix deep into the tissue blocks resulting in focal loss of aggrecan and other matrix components from the more central regions of the blocks. This was evident in toluidine blue stained sectionsof immature tibial articular cartilage where loss of glycosaminoglycan was significant in Histochoice fixed tissues. Histochoice fixation worked well, however, in the aggrecan and perlecan immunohistology applications where its non-cross-linking traits were conducive to epitope retrieval and identification by primary antibodies to extracellular matrix components.To place an order or receive technical assistance Order/Customer Service: /orderTechnical Service: /techserviceSafety-related Information: /safetycenter Copyright © 2017 Merck KGaA.

3M Friction Shims 产品说明说明书
3M Advanced Materials DivisionIntroductionThe demand for maximum powerdensity, i.e. the transmission of greater force and torque in increasingly compact designs, poses a major challenge to engineers across a variety of industries. 3M Technical Ceramics manufactures friction-enhancing solutions for joining components to withstand highershear forces or transmit higher torque in bolt connections. 3M ™ Friction Shims offer a simple and cost-effective way to reliably transmit up to 4x higher torques or forces thanconventional systems without requiring modifications to the joint design.3M friction shims are metal foils with a coating of electroless nickel embedded with diamond particles. The diamonds indent into the metal mating surface and create a micro-scale interlock. The shims themselves are easy to assemble and can bereused after disassembly. 3M friction shims are thin enough to fit within close engineering tolerances, creating possibilities for lightweight compact design while increasing maximum load and peak torque in bolt connections.3M friction shims have proveneffective in a wide variety of industries, including general mechanicalengineering, machine tools, marine engineering, wind and water power generators, turbines, automotive engineering and motor sports. Our technical specialists have many years of application experience, and conduct in-house laboratory and bench tests to ensure that 3M friction shims meet our customers’ specific requirements.Features• I ncreases the coefficient of static friction• F unction of 3M friction shims is not affected by an oil film • Can be easily retrofitted • Prevents fretting • Highly reproducible • C olor option for distinctive appearance• S him geometries can be tailored to customer specificationApplication• Frictional joints • Flange joints• Joints with central bolt • Bolt connections • Fastener systemsApplication NotesWhen 3M friction shims are used please note:• F or maximum performance, the mating surfaces must have roughness values Rz as given in the technical data sheet.• C ontact pressure of at least 50 MPa is recommended.• W hen designing the joint,ensure that the counterparts to be joined are in full contact.• O nly use in applications with static friction in the contact area.• T he coefficient of static friction depends on a large number ofdifferent parameters.
