AffiELISA® Mouse PIICP Kit: High-Resolution Procollagen II C-Terminal Propeptide ELISA Detection

The AffiELISA® Mouse PIICP Kit uses competitive inhibition enzyme immunoassay technique. The provided microtiter plate comes pre-coated with Procollagen II C-Terminal Propeptide (PIICP) protein. To perform the assay, standards or samples are added to designated wells on the microtiter plate. Subsequently, a biotin-conjugated antibody specific to Procollagen II C-Terminal Propeptide (PIICP) is introduced. Avidin conjugated to Horseradish Peroxidase (HRP) is then added to each well, followed by an incubation period. Afterward, the TMB substrate solution is added, initiating an enzyme-substrate reaction. To conclude the reaction, a sulphuric acid solution is introduced, causing a color change that can be measured spectrophotometrically at a wavelength of 450nm ± 10nm. By comparing the optical density (OD) of the samples to the standard curve, the concentration of Procollagen II C-Terminal Propeptide (PIICP) in the samples can be determined.
