尿微量白蛋白(胶体金法)技术要求
尿微量白蛋白(胶体金法)技术要求哎呀，说起尿微量白蛋白（胶体金法）技术要求，这可真是个技术活儿，得慢慢道来。
首先，咱们得聊聊这个尿微量白蛋白是个啥。
简单来说，它就是尿液里的一种蛋白质，正常情况下，尿液里是不应该有这种蛋白质的。
但是，如果肾脏出了点小问题，比如糖尿病肾病啊，高血压肾病啊，这种蛋白质就会偷偷溜进尿液里。
所以，检测这个尿微量白蛋白，对于早期发现肾脏问题还是挺重要的。
接下来，咱们得说说这个胶体金法。
这是一种检测方法，用一种叫做胶体金的东西来标记抗体，然后通过化学反应来检测尿液中的微量白蛋白。
这个方法的好处是灵敏度高，操作简便，结果也快。
那么，这个技术要求具体是啥呢？首先，你得有个干净的尿样。
这个尿样得是新鲜的，最好是早上第一次尿，因为这时候尿液浓度最高，检测结果最准确。
然后，你得有个靠谱的检测试剂盒，这个试剂盒里包含了胶体金标记的抗体和一些其他必要的化学试剂。
操作的时候，你得按照说明书来，一步步来。
首先，把尿样滴到试剂盒的测试区，然后等个几分钟，让尿液和试剂充分反应。
这个过程中，你可能会看到一些颜色变化，这就是胶体金抗体和尿微量白蛋白结合的结果。
最后，你得对照试剂盒上的对照线，看看测试区的颜色变化，以此来判断尿微量白蛋白的浓度。
这个过程中，你得注意几个细节。
首先，操作的时候手要干净，别让脏东西污染了尿样或者试剂。
其次，等待时间要准确，太短了反应不充分，太长了结果可能会受影响。
最后，读结果的时候要仔细，别因为颜色变化不明显就忽略了。
总的来说，尿微量白蛋白（胶体金法）技术要求就是：干净的尿样，靠谱的试剂盒，准确的操作，仔细的结果解读。
虽然听起来有点复杂，但只要按照步骤来，还是挺简单的。
这个技术对于早期发现和监测肾脏问题还是挺有帮助的，希望我说的这些对你有所帮助。

cusabio 微量白蛋白尿(MAU ALB)检测试剂盒使用说明书
Human microalbunminuria(MAU/ALB) ELISA kit Catalog Number. CSB-E08970hFor the quantitative determination of human microalbunminuria(MAU/ALB) concentrations in serum, plasma, urine.This package insert must be read in its entirety before using this product.If You Have ProblemsTechnical Service Contact informationPhone: 86-27-87582341Fax: 86-27-87196150Email:****************Web: In order to obtain higher efficiency service, please ready to supply the lot numberof the kit to us (found on the outside of the box).1PRINCIPLE OF THE ASSAYThis assay employs the competitive inhibition enzyme immunoassay technique. Antibody specific for MAU has been pre-coated onto a microplate. Standards and samples are pipetted into the wells with biotin-conjugated MAU. A competitive inhibition reaction is launched between MAU (Standards or samples) and biotin-conjugated MAU with the pre-coated MAU antibody. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound reagent, a substrate solution is added to the wells and color develops in opposite to the amount of MAU bound in the initial step. The color development is stopped and the intensity of the color is measured.DETECTION RANGE0.078 µg/ml-5 µg/ml.SENSITIVITYThe minimum detectable dose of human MAU is typically less than 0.019 µg/ml. The sensitivity of this assay, or Lower Limit of Detection (LLD) was defined as the lowest human MAU concentration that could be differentiated from zero.SPECIFICITYThis assay has high sensitivity and excellent specificity for detection of human MAU. No significant cross-reactivity or interference between human MAU and analogues was observed.Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between human MAU and all the analogues, therefore, cross reaction may still exist.2PRECISIONIntra-assay Precision (Precision within an assay): CV%<8%Three samples of known concentration were tested twenty times on one plate to assess.Inter-assay Precision (Precision between assays):CV%<10%Three samples of known concentration were tested in twenty assays to assess.LIMITATIONS OF THE PROCEDUREFOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC PROCEDURES.The kit should not be used beyond the expiration date on the kit label.Do not mix or substitute reagents with those from other lots or sources.If samples generate values higher than the highest standard, dilute the samples with Sample Diluent and repeat the assay.Any variation in Sample Diluent, operator, pipetting technique, washing technique, incubation time or temperature, and kit age can cause variation in binding.This assay is designed to eliminate interference by soluble receptors, binding proteins, and other factors present in biological samples. Until all factors have been tested in the Immunoassay, the possibility of interference cannot be excluded.3MATERIALS PROVIDEDReagents QuantityAssay plate (12 x 8 coated Microwells) 1(96 wells) Standard (Freeze dried) 2Biotin-conjugate (100 x concentrate) 1 x 60 µlHRP-avidin (100 x concentrate) 1 x 120 µlBiotin-conjugate Diluent 1 x 10 mlHRP-avidin Diluent 1 x 20 ml Sample Diluent 2 x 20 mlWash Buffer (25 x concentrate) 1 x 20 mlTMB Substrate 1 x 10 mlStop Solution 1 x 10 ml Adhesive Strip (For 96 wells) 4Instruction manual 1STORAGEUnopenedkitStore at 2 - 8°C.

Wear eye, hand, face, and clothing protection when using this material.5SAMPLE COLLECTION AND STORAGESerum Use a serum separator tube (SST) and allow samples to clot for30 minutes before centrifugation for 15 minutes at 1000 x g, 2 - 8°C.Remove serum and assay immediately or aliquot and store samples at -20°C or -80°C. Avoid repeated freeze-thaw cycles. Centrifuge the sample again after thawing before the assay.Plasma Collect plasma using EDTA, or heparin as an anticoagulant.Centrifuge for 15 minutes at 1000 x g, 2 - 8°C within 30 minutes of collection. Assay immediately or aliquot and store samples at -20°C or -80°C. Avoid repeated freeze-thaw cycles. Centrifuge the sample again after thawing before the assay.Urine Use a sterile container to collect urine samples. Remove any particulates by centrifugation for 15 minutes at 1000xg, 2 - 8°C and assay immediately or aliquot and store samples at -20°C or -80°C. Avoid repeated freeze-thaw cycles. Centrifuge again before assaying to remove any additional precipitates that may appear after storage.SAMPLE PREPARATIONRecommend to dilute the serum or plasma samples 50000-fold before test.The suggested 50000-fold dilution can be achieved by adding 2µl sample to 398µl of normal saline. Complete the 50000-fold dilution by adding 2µl of this solution to 498µl of Sample Diluent. The recommended dilution factor is for reference only. The optimal dilution factor should be determined by users according to their particular experiments.Recommend to dilute the urine samples with Sample Diluent(1:40) before test. The suggested 40-fold dilution can be achieved by adding 6µl sample to 234µl of Sample Diluent. The recommended dilution factor is for reference only. The optimal dilution factor should be determined by users according to their particular experiments6Note:1. CUSABIO is only responsible for the kit itself, but not for the samplesconsumed during the assay. The user should calculate the possible amount of the samples used in the whole test. Please reserve sufficient samples in advance.2. Samples to be used within 5 days may be stored at 2-8°C, otherwisesamples must be stored at -20°C (≤1month) or -80°C (≤2month) to avoid loss of bioactivity and contamination.3. Grossly hemolyzed samples are not suitable for use in this assay.4. If the samples are not indicated in the manual, a preliminary experiment todetermine the validity of the kit is necessary.5. Please predict the concentration before assaying. If values for these arenot within the range of the standard curve, users must determine the optimal sample dilutions for their particular experiments.6. Tissue or cell extraction samples prepared by chemical lysis buffer maycause unexpected ELISA results due to the impacts of certain chemicals.7. Owing to the possibility of mismatching between antigen from otherresource and antibody used in our kits (e.g., antibody targets conformational epitope rather than linear epitope), some native or recombinant proteins from other manufacturers may not be recognized by our products.8. Influenced by the factors including cell viability, cell number and alsosampling time, samples from cell culture supernatant may not be detected by the kit.9. Fresh samples without long time storage are recommended for the test.Otherwise, protein degradation and denaturalization may occur in those samples and finally lead to wrong results.7REAGENT PREPARATIONNote:Kindly use graduated containers to prepare the reagent. Please don't prepare the reagent directly in the Diluent vials provided in the kit. Bring all reagents to room temperature (18-25°C) before use for 30min.Prepare fresh standard for each assay. Use within 4 hours and discard after use.Making serial dilution in the wells directly is not permitted.Please carefully reconstitute Standards according to the instruction, and avoid foaming and mix gently until the crystals have completely dissolved.To minimize imprecision caused by pipetting, use small volumes and ensure that pipettors are calibrated. It is recommended to suck more than 10µl for once pipetting.Distilled water is recommended to be used to make the preparation for reagents. Contaminated water or container for reagent preparation will influence the detection result.1. Biotin-conjugate (1x) - Centrifuge the vial before opening.Biotin-conjugate requires a 100-fold dilution. A suggested 100-fold dilution is 10 µl of Biotin-conjugate + 990 µl of Biotin-conjugate Diluent.2. HRP-avidin (1x) - Centrifuge the vial before opening.HRP-avidin requires a 100-fold dilution. A suggested 100-fold dilution is 10 µl of HRP-avidin + 990 µl of HRP-avidin Diluent.3. Wash Buffer(1x)- If crystals have formed in the concentrate, warm up toroom temperature and mix gently until the crystals have completely dissolved. Dilute 20 ml of Wash Buffer Concentrate (25 x) into deionized or distilled water to prepare 500 ml of Wash Buffer (1 x).894.StandardCentrifuge the standard vial at 6000-10000rpm for 30s.Reconstitute the Standard with 1.0 ml of Sample Diluent . Do not substitute other diluents. This reconstitution produces a stock solution of 5 µg/ml. Mix the standard to ensure complete reconstitution and allow the standard to sit for a minimum of 15 minutes with gentle agitation prior to making dilutions.Pipette 150 µl of Sample Diluent into each tube (S0-S6). Use the stock solution to produce a 2-fold dilution series (below). Mix each tube thoroughly before the next transfer. The undiluted Standard serves as the high standard (5 µg/ml). Sample Diluent serves as the zero standard (0 µg/ml).Tube S7 S6 S5S4 S3 S2 S1 S0 µg/ml52.51.250.6250.3120.1560.078ASSAY PROCEDUREBring all reagents and samples to room temperature before use. Centrifuge the sample again after thawing before the assay.It is recommended that all samples and standards be assayed in duplicate.1. Prepare all reagents, working standards, and samples as directed in theprevious sections.2. Refer to the Assay Layout Sheet to determine the number of wells to beused and put any remaining wells and the desiccant back into the pouch and seal the ziploc, store unused wells at 4°C.3. Set a Blank well without any solution.4. Add 50µl of standard and sample per well.5. Add 50µl of Biotin-conjugate(1x) to each well(not to Blank well). Coverwith a new adhesive strip. Incubate for 60 minutes at 37°C.(Biotin-conjugate(1x) may appear cloudy. Warm up to room temperature and mix gently until solution appears uniform.)6. Aspirate each well and wash, repeating the process two times for a total ofthree washes. Wash by filling each well with Wash Buffer (200µl) using a squirt bottle, multi-channel pipette, manifold dispenser, or autowasher, and let it stand for 2 minutes, complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Buffer by aspirating or decanting. Invert the plate and blot it against clean paper towels.7. Add 100µl of HRP-avidin(1x) to each well(not to Blank well). Cover themicrotiter plate with a new adhesive strip. Incubate for 60 minutes at 37°C.8. Repeat the aspiration/wash process for five times as in step 6.9. Add 90µl of TMB Substrate to each well. Incubate for 20 minutes at 37°C.Protect from light.10. Add 50µl of Stop Solution to each well, gently tap the plate to ensurethorough mixing.1011. Determine the optical density of each well within 5 minutes, using amicroplate reader set to 450 nm. If wavelength correction is available, set to 540 nm or 570 nm. Subtract readings at 540 nm or 570 nm from the readings at 450 nm. This subtraction will correct for optical imperfections in the plate. Readings made directly at 450 nm without correction may be higher and less accurate.*Samples may require dilution. Please refer to Sample Preparation section. Note:1. The final experimental results will be closely related to validity of theproducts, operation skills of the end users and the experimental environments.2. Samples or reagents addition: Please use the freshly prepared Standard.Please carefully add samples to wells and mix gently to avoid foaming. Do not touch the well wall as possible. For each step in the procedure, total dispensing time for addition of reagents or samples to the assay plate should not exceed 10 minutes. This will ensure equal elapsed time for each pipetting step, without interruption. Duplication of all standards and specimens, although not required, is recommended. To avoid cross-contamination, change pipette tips between additions of each standard level, between sample additions, and between reagent additions.Also, use separate reservoirs for each reagent.3. Incubation: To ensure accurate results, proper adhesion of plate sealersduring incubation steps is necessary. Do not allow wells to sit uncovered for extended periods between incubation steps. Once reagents have been added to the well strips, DO NOT let the strips DRY at any time during the assay. Incubation time and temperature must be observed.4. Washing: The wash procedure is critical. Complete removal of liquid ateach step is essential to good performance. After the last wash, remove any remaining Wash Solution by aspirating or decanting and remove any drop of water and fingerprint on the bottom of the plate. Insufficient washing will result in poor precision and falsely elevated absorbance reading. When using an automated plate washer, adding a 30 second soak period following the addition of wash buffer, and/or rotating the plate 180 degrees between wash steps may improve assay precision.115. Controlling of reaction time: Observe the change of color after adding TMBSubstrate (e.g. observation once every 10 minutes), TMB Substrate should change from colorless or light blue to gradations of blue. If the color is too deep, add Stop Solution in advance to avoid excessively strong reaction which will result in inaccurate absorbance reading.6. TMB Substrate is easily contaminated. TMB Substrate should remaincolorless or light blue until added to the plate. Please protect it from light.7. Stop Solution should be added to the plate in the same order as the TMBSubstrate. The color developed in the wells will turn from blue to yellow upon addition of the Stop Solution. Wells that are green in color indicate that the Stop Solution has not mixed thoroughly with the TMB Substrate.1213ASSAY PROCEDURE SUMMARY*Samples may require dilution. Please refer to Sample Preparation section.CALCULATION OF RESULTSUsing the professional soft "Curve Expert" to make a standard curve is recommended, which can be downloaded from our web.Average the duplicate readings for each standard and sample and subtract the average optical density of Blank.Create a standard curve by reducing the data using computer software capable of generating a four parameter logistic (4-PL) curve-fit. As an alternative, construct a standard curve by plotting the mean absorbance for each standard on the x-axis against the concentration on the y-axis and draw a best fit curve through the points on the graph. The data may be linearized by plotting the log of the MAU concentrations versus the log of the O.D. and the best fit line can be determined by regression analysis. This procedure will produce an adequate but less precise fit of the data.If samples have been diluted, the concentration read from the standard curve must be multiplied by the dilution factor.14人尿微量白蛋白(MAU/ALB)酶联免疫试剂盒使用说明书【产品编号】CSB-E08970h【预期应用】ELISA法定量测定人血清、血浆、尿液中MAU含量。
