Rat C1INH (Complement 1 Inhibitor) ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Rat C1INH. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat C1INH. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Rat C1INH, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat C1INH in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Serine protease inhibitor, which acrs as a regulator of the classical complement pathway. Forms a proteolytically inactive stoichiometric complex with the C1r or C1s proteases. May also regulate blood coagulation, fibrinolysis and the generation of kinins. Very efficient inhibitor of FXIIa. Inhibits chymotrypsin and kallikrein [The Uniprot Consortium]
