The Transcription Factor RelB （RELB） BioAssay ELISA Kit （human） is a quantitative sandwich assay for the detection of Transcription Factor RelB in human serum，plasma，tissue homogenates and other biological fluids.Detection Range： 0.156-10ng/mlSensitivity：<0.094ngl/mlPrecision： Intra-Assay CV： <8%Inter-Assay CV： <10%Kit Components：*358541A： Microtiter Strips，8x12 wells.*358541B： Standard，2x1 vial358541C： Sample/Standard Dilution Buffer，1x20ml358541D： Antibody-Biotin Concentrate，1x120ul358541E： Antibody Dilution Buffer，1x10ml358541F： Streptavidin-HRP Conjugate （SABC），1x120ul358541G： SABC Dilution Buffer，1x10ml358541H： TMB Substrate，1x10ml358541J： Stop Solution，1x10ml358541K： Wash Buffer，25X，1x30mlStorage and Stability：Store unopened *358541A at 4ºC; store at -20ºC once opened. Store unopened *358541B at 4°C; once reconstituted store at 4°C for up to 12 hours or at -20°C for up to 48 hours. Store other components at 4°C. Kit is stable for 6 months after receipt. For maximum recovery of product，centrifuge the original vials after thawing and prior to removing the cap.Assay Principle：The microtiter plate provided in this kit has been pre-coated with an antibody specific to Transcription Factor RelB. Standards and samples are added to the appropriate microtiter plate wells followed by a biotin-conjugated antibody specific to Transcription Factor RelB. Streptavidin conjugated to Horseradish Peroxidase （HRP） is added to each microplate well and incubated. After TMB substrate solution is added，only those wells that contain Transcription Factor RelB，Biotin-conjugated antibody and enzyme-conjugated Streptavidin complex will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulfuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm±10nm. The concentration of Transcription Factor RelB in the sample is then determined by comparing the O.D. of the sample to the standard curve.Assay Summary：1. Wash plate 2 times before adding standards，samples and control （zero） to wells.2. Add 100ul standard or sample to each well and incubate for 90 minutes at 37°C. Aspirate and wash 2 times.3. Add 100ul Antibody-Biotin working solution to each well and incubate for 60 minutes at 37°C4. Aspirate and wash 3 times.5. Add 100ul SABC working solution to each well. Incubate for 30 minutes at 37°C6. Aspirate and wash 5 times.7. Add 90ul TMB substrate. Incubate 15-30 minutes at 37°C8. Add 50ul Stop Solution. Read at 450nm immediately.9. Calculate results.
