Assay-Prinzip
Porcine Procollagen Type II C-Terminal Propeptide/PIICP ELISA Kit (A327092) employs the sandwich enzyme immunoassay technique for the quantitative measurement of porcine Procollagen Type II C-Terminal Propeptide/PIICP in serum, plasma, and other biological fluids. An antibody specific for Procollagen Type II C-Terminal Propeptide/PIICP has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the Procollagen Type II C-Terminal Propeptide/PIICP present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-Procollagen Type II C-Terminal Propeptide/PIICP Antibody, which binds the captured Procollagen Type II C-Terminal Propeptide/PIICP present in each well. Following incubation, unbound biotinylated detection antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is proportional to the amount of Procollagen Type II C-Terminal Propeptide/PIICP captured in each well. The concentration of Procollagen Type II C-Terminal Propeptide/PIICP can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
