Sample Type：Serum，plasma，tissue homogenates and other biological fluids.Intended Use：Competitive ELISA，Coated with AntigenSensitivity：<46.875pg/mlRange：78.125-5000pg/mlSpecificity：UniversalTest Principle：This BioAssay ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with Vasopressin. During the reaction，Vasopressin in the sample or standard competes with a fixed amount of Vasopressin on the solid phase supporter for sites on the Biotinylated Detection Antibody specific to Vasopressin. Excess conjugate and unbound sample or standard are washed from the plate，and HRP-Streptavidin （SABC） is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm. The concentration of Vasopressin in the samples is then determined by comparing the O.D. of the samples to the standard curve.Kit Components：Micro ELISA Plate （Dismountable），8x12Lyophilized Standard，2xvialSample/Standard dilution buffer，20mlBiotin-detection antibody （Concentrated），60ulAntibody dilution buffer，10mlHRP-Streptavidin Conjugate （SABC），120ulSABC dilution buffer，10mlTMB substrate，10mlStop solution，10mlWash buffer （25X），30mlPlate Sealer，5xpiecesProduct Description，1xcopyStorage and Stability：Store powder at 4°C liquid at -20°C.
