CSB-E04486h人活化素A(ACV-A)ELISA Kit

1Human Activin A （ACV-A）ELISA KitCatalog No. CSB-E04486h（96T） This immunoassay kit allows for the in vitro quantitative determination of humanACV-A concentrations in serum, plasma. 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 with anantibody specific to ACV-A. Standards or samples are then addedto the appropriate microtiter plate wells with a HorseradishPeroxidase （HRP）-conjugated antibody preparation specific forACV-A ａnd incubated. Then substrate solution A ａnd B are addedto each well. Only those wells that contain ACV-A, HRP-conjugatedantibody will exhibit a change in color. The enzyme-substratereaction is terminated by the addition of a sulphuric acid solutionand the color change is measured spectrophotometrically at awavelength of 450 nm ± 2 nm. The concentration of ACV-A in thesamples is then determined by comparing the O.D. of the samplesto the standard curve.DETECTION RANGE66.6 pg/ml-2000 pg/ml. The standard curve concentrations used forthe ELISA’s were 2000 pg/ml, 1000 pg/ml, 500 pg/ml, 166.6pg/ml,66.6pg/ml.SPECIFICITYThis assay recognizes human ACV-A. No significantcross-reactivity or interference was observed.3SENSITIVITYThe minimum detectable dose of human ACV-A is typically lessthan 16.7 pg/ml.The sensitivity of this assay, or Lower Limit of Detection （LLD） wasdefined as the lowest concentration that could be differentiatedfrom zero.MATERIALS PROVIDEDReagent QuantityAssay plate 1Standard（S1-S5） 5HRP-conjugate 1 x 6 mlWash Buffer1 x 15 ml（20×concentrate）Substrate A 1 x 7 mlSubstrate B 1 x 7 mlStop Solution 1 x 7 mlStandard S1 S2 S3 S4 S5Concentration（pg/ml）66.6 166.6 500 1000 20004STORAGE1. Unopened test kits should be stored at 2-8C upon receipt andthe microtiter plate should be kept in a sealed bag. The test kitmay be used throughout the expiration date of the kit, provided itis stored as prescribed above. Refer to the package label for theexpiration date.2. Opened test plate should be stored at 2-8C in the aluminum foilbag with desiccants to minimize exposure to damp air. The kitswill remain stable until the expiring date shown, provided it isstored as prescribed above.3. A microtiter plate reader with a bandwidth of 10 nm or less andan optical density range of 0-3 OD or greater at 450nmwavelength is acceptable for use in absorbance measurement.REAGENT PREPARATION1. Bring all reagents ａnd plate to room temperature for at least 30minutes before use. Unused wells need store at 2-8°C andavoid sunlight.2. Wash Buffer If crystals have formed in the concentrate, warmto room temperature ａnd mix gently until the crystals havecompletely dissolved. Dilute 15 ml of Wash Buffer Concentrateinto deionized or distilled water to prepare 300 ml of WashBuffer.5OTHER SUPPLIES REQUIRED Microplate reader capable of measuring absorbance at 450 nm,with the correction wavelength set at 540 nm or 570 nm. Pipettes ａnd pipette tips. Deionized or distilled water. Squirt bottle, manifold dispenser, or automated microplatewasher. An incubator which can provide stable incubation conditions upto 37°C±0.5°C.SAMPLE COLLECTION AND STORAGE Serum Use a serum separator tube （SST）ａnd allow samplesto clot for 30 minutes before centrifugation for 15 minutes at1000 g. Remove serum ａnd assay immediately or aliquot andstore samples at -20°C. Centrifuge the sample again afterthawing before the assay. Avoid repeated freeze-thaw cycles. Plasma Collect plasma using citrate, EDTA, or heparin as ananticoagulant. Centrifuge for 15 minutes at 1000 g within 30minutes of collection. Assay immediately or aliquot ａnd storesamples at -20°C. Centrifuge the sample again after thawingbefore the assay. Avoid repeated freeze-thaw cycles.Note: Grossly hemolyzed samples are not suitable for use in this assay.6ASSAY PROCEDUREBring all reagents ａnd samples to room temperature before use. It is recommendedthat all samples, standards, ａnd controls be assayed in duplicate. All the reagentsshould be added directly to the liquid level in the well. The pipette should avoidcontacting the inner wall of the well.1. Standard Reconstitute the Standards with 0.5 ml of ddH2O,respectively. Allow the standard to sit for a minimum of 15minutes with gentle agitation prior to use.2. Set a Blank well without any solution. Add 50μl of Standard orSample per well. Standard need test in duplicate.3. Add 50μl of HRP-conjugate to each well （not to Blank well）.Mix well ａnd then incubate for 1 hour at 37°C.4. Complete remove the liquid. Then fill each well with WashBuffer （about 200μl）, stay for 10 seconds ａnd Spinning. Repeatthe process for a total of three washes. Complete removal ofliquid at each step is essential to good performance. After thelast wash, remove any remaining Wash Buffer by aspirating ordecanting. Invert the plate ａnd blot it against clean papertowels.5. Add 50μl of Substrate A ａnd 50μl of Substrate B to each well,mix well. Incubate for 15 minutes at 37°C. Keeping the plateaway from drafts ａnd other temperature fluctuations in the dark.76. Add 50μl of Stop Solution to each well when the first four wellscontaining the highest concentration of standards developobvious blue color. If color change does not appear uniform,gently tap the plate to ensure thorough mixing.7. Determine the optical density of each well within 10 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 against theconcentration on the y-axis ａnd draw a best fit curve through thepoints on the graph. The data may be linearized by plotting the logof the ACV-A concentrations versus the log of the O.D. ａnd thebest fit line can be determined by regression analysis. Thisprocedure will produce an adequate but less precise fit of the data.If samples have been diluted, the concentration read from thestandard curve must be multiplied by the dilution factor.8LIMITATIONS OF THE PROCEDURE The kit should not be used beyond the expiration date on the kitlabel. Do not mix or substitute reagents with those from other lots orsources. If samples generate values higher than the highest standard,dilute the samples with the appropriate Diluent ａnd repeat theassay. Any variation in operator, pipetting technique, washingtechnique, incubation time or temperature, ａnd kit age cancause 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.TECHNICAL HINTS Centrifuge vials before opening to collect contents. When mixing or reconstituting protein solutions, always avoidfoaming.9 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 from light.Substrate Solution should change from colorless or light blue togradations of blue. Stop Solution should be added to the plate in the same order asthe Substrate Solution. The color developed in the wells willturn from blue to yellow upon addition of the Stop Solution.Wells that are green in color indicate that the Stop Solution hasnot mixed thoroughly with the Substrate Solution.
