CSB-E04489h人血管緊張素轉化酶2(ACE2)ELISA Kit
1Human angiotensin convertingenzyme 2（ACE2）ELISA KitCatalog No. CSB-E04489h（96 T） This immunoassay kit allows for the in vitro quantitative determination of humanACE2 concentrations in serum, plasma ａnd cell culture supernates. Expiration date six months from the date of manufacture FOR RESEARCH USE ONLY. NOT FOR USE IN DIAGNOSTIC PROCEDURES.2PRINCIPLE OF THE ASSAYThe microtiter plate provided in this kit has been pre-coated withan antibody specific to ACE2. Standards or samples are thenadded to the appropriate microtiter plate wells with abiotin-conjugated antibody preparation specific for ACE2 andAvidin conjugated to Horseradish Peroxidase （HRP） is added toeach microplate well ａnd incubated. Then a TMB （3,3＇,5,5＇tetramethyl-benzidine） substrate solution is added to each well.Only those wells that contain ACE2, biotin-conjugated antibodyand enzyme-conjugated Avidin will exhibit a change in color. Theenzyme-substrate reaction is terminated by the addition of asulphuric acid solution ａnd the color change is measuredspectrophotometrically at a wavelength of 450 nm ± 2 nm. Theconcentration of ACE2 in the samples is then determined bycomparing the O.D. of the samples to the standard curve.DETECTION RANGE0.156 ng/ml-10 ng/ml. The standard curve concentrations usedfor the ELISA’s were 10 ng/ml, 5 ng/ml, 2.5 ng/ml, 1.25 ng/ml,0.625 ng/ml, 0.312 ng/ml, 0.156 ng/ml.3SPECIFICITYThis assay recognizes human ACE2. No significantcross-reactivity or interference was observed.SENSITIVITYThe minimum detectable dose of human ACE2 is typically lessthan 0.04 ng/ml.The sensitivity of this assay, or Lower Limit of Detection （LLD）was defined as the lowest protein concentration that could bedifferentiated from zero.MATERIALS PROVIDEDReagent QuantityAssay plate 1Standard 2Sample Diluent 1 x 20 mlBiotin-antibody Diluent 1 x 10 mlHRP-avidin Diluent 1 x 10 mlBiotin-antibody 1 x 120μlHRP-avidin 1 x 120μlWash Buffer1 x 20 ml（25×concentrate）TMB Substrate 1 x 10 mlStop Solution 1 x 10 ml4STORAGE1. Unopened test kits should be stored at 2-8C upon receiptand the microtiter plate should be kept in a sealed bag. Thetest kit may be used throughout the expiration date of the kit,provided it is stored as prescribed above. Refer to thepackage label for the expiration date.2. Opened test plate should be stored at 2-8C in the aluminumfoil bag with desiccants to minimize exposure to damp air. Thekits will remain stable until the expiring date shown, provided itis stored as prescribed above.3. A microtiter plate reader with a bandwidth of 10 nm or lessand an optical density range of 0-3 OD or greater at 450nmwavelength is acceptable for use in absorbancemeasurement.REAGENT PREPARATIONBring all reagents to room temperature before use.1. Wash Buffer If crystals have formed in the concentrate,warm up to room temperature ａnd mix gently until thecrystals have completely dissolved. Dilute 20 ml of WashBuffer Concentrate into deionized or distilled water to prepare500 ml of Wash Buffer.52. Standard Centrifuge the standard vial at 6000-10000rpmfor 30s. Reconstitute the Standard with 1.0 ml of SampleDiluent. This reconstitution produces a stock solution of 10ng/ml. Allow the standard to sit for a minimum of 15 minuteswith gentle agitation prior to making serial dilutions. Theundiluted standard serves as the high standard （10 ng/ml）.The Sample Diluent serves as the zero standard （0 ng/ml）.Prepare fresh for each assay. Use within 4 hours ａnd discardafter use.3. Biotin-antibody Centrifuge the vial before opening. Diluteto the working concentration using Biotin-antibodyDiluent（1:100）, respectively.4. HRP-avidin Centrifuge the vial before opening. Dilute to theworking concentration using HRP-avidin Diluent（1:100）,respectively.Precaution: The Stop Solution provided with this kit is an acid solution. Weareye, hand, face, ａnd clothing protection when using this material.OTHER SUPPLIES REQUIRED Microplate reader capable of measuring absorbance at 450nm, with the correction wavelength set at 540 nm or 570 nm. Pipettes ａnd pipette tips. Deionized or distilled water.6 Squirt bottle, manifold dispenser, or automated microplatewasher. An incubator which can provide stable incubation conditionsup to 37°C±0.5°C.SAMPLE COLLECTION AND STORAGE Serum Use a serum separator tube （SST） ａnd allowsamples to clot for 30 minutes before centrifugation for 15minutes at 1000 g. Remove serum ａnd assay immediately oraliquot ａnd store samples at -20°C. Centrifuge the sampleagain after thawing before the assay. Avoid repeatedfreeze-thaw cycles. Plasma Collect plasma using citrate, EDTA, or heparin asan anticoagulant. Centrifuge for 15 minutes at 1000 g within30 minutes of collection. Assay immediately or aliquot andstore samples at -20°C. Centrifuge the sample again afterthawing before the assay. Avoid repeated freeze-thaw cycles. Cell Culture Supernates Remove particulates bycentrifugation for 15 minutes at 1000 x g, 2 - 8°C ａnd assayimmediately or aliquot ａnd store samples at -20° C or -80°C.Avoid repeated freeze-thaw cycles.Note: Grossly hemolyzed samples are not suitable for use in this assay.7ASSAY PROCEDUREBring all reagents ａnd samples to room temperature before use. It isrecommended that all samples, standards, ａnd controls be assayed in duplicate.All the reagents should be added directly to the liquid level in the well. Thepipette should avoid contacting the inner wall of the well.1. Add 100μl of Standard, Blank, or Sample per well. Cover withthe adhesive strip. Incubate for 2 hours at 37°C.2. Remove the liquid of each well, don’t wash.3. Add 100μl of Biotin-antibody working solution to each well.Incubate for 1 hour at 37°C. Biotin-antibody workingsolution may appear cloudy. Warm up to room temperatureand mix gently until solution appears uniform.4. Aspirate each well ａnd wash, repeating the process threetimes for a total of three washes. Wash: Fill each well withWash Buffer （200μl） ａnd let it stand for 2 minutes, thenremove the liquid by flicking the plate over a sink. Theremaining drops are removed by patting the plate on a papertowel. Complete removal of liquid at each step is essential togood performance.5. Add 100μl of HRP-avidin working solution to each well.Cover the microtiter plate with a new adhesive strip. Incubatefor 1 hour at 37°C.6. Repeat the aspiration ａnd wash five times as step 4.87. Add 90μl of TMB Substrate to each well. Incubate for 10-30minutes at 37°C. Keeping the plate away from drafts andother temperature fluctuations in the dark.8. Add 50μl of Stop Solution to each well when the first fourwells containing the highest concentration of standardsdevelop obvious blue color. If color change does not appearuniform, gently tap the plate to ensure thorough mixing.9. Determine the optical density of each well within 30 minutes,using a microplate reader set to 450 nm.CALCULATION OF RESULTSUsing the professional soft "Curve Exert 1.3" to make a standard curve isrecommended, which can be downloaded from our web.Average the duplicate readings for each standard, control, andsample ａnd subtract the average zero standard optical density.Create a standard curve by reducing the data using computersoftware capable of generating a four parameter logistic （4-PL）curve-fit. As an alternative, construct a standard curve by plottingthe mean absorbance for each standard on the x-axis againstthe concentration on the y-axis ａnd draw a best fit curve throughthe points on the graph. The data may be linearized by plottingthe log of the ACE2 concentrations versus the log of the O.D.and the best fit line can be determined by regression analysis.9This procedure will produce an adequate but less precise fit ofthe data. If samples have been diluted, the concentration readfrom the standard curve must be multiplied by the dilution factor.LIMITATIONS OF THE PROCEDURE The kit should not be used beyond the expiration date on thekit label. Do not mix or substitute reagents with those from other lots orsources. It is important that the Standard Diluent selected for thestandard curve be consistent with the samples beingassayed. If samples generate values higher than the highest standard,dilute the samples with the appropriate Standard Diluent andrepeat the assay. Any variation in Standard Diluent, operator, pipettingtechnique, washing technique, incubation time ortemperature, ａnd kit age can cause variation in binding. This assay is designed to eliminate interference by solublereceptors, binding proteins, ａnd other factors present inbiological samples. Until all factors have been tested in theImmunoassay, the possibility of interference cannot beexcluded.1 0TECHNICAL HINTS Centrifuge vials before opening to collect contents. When mixing or reconstituting protein solutions, always avoidfoaming. To avoid cross-contamination, change pipette tips betweenadditions of each standard level, between sample additions,and between reagent additions. Also, use separate reservoirsfor each reagent. When using an automated plate washer, adding a 30 secondsoak period following the addition of wash buffer, and/orrotating the plate 180 degrees between wash steps mayimprove assay precision. To ensure accurate results, proper adhesion of plate sealersduring incubation steps is necessary. Substrate Solution should remain colorless or light blue untiladded to the plate. Keep Substrate Solution protected fromlight. Substrate Solution should change from colorless or lightblue to gradations of blue. Stop Solution should be added to the plate in the same orderas the Substrate Solution. The color developed in the wellswill turn from blue to yellow upon addition of the Stop Solution.Wells that are green in color indicate that the Stop Solutionhas not mixed thoroughly with the Substrate Solution.
