Method Description
The assay is based on chemiluminescence technology. Twenty microliters of patient sample or calibrator are added to a diluent, and a portion incubated with a biotinylated anti-procollagen type I N-terminal propeptide (PINP) monoclonal antibody, an acridinium labelled monoclonal antibody, streptavidin labelled magnetic particles and an assay buffer. The magnetic particles are captured using a magnet, and a wash step is performed to remove any unbound analyte. Trigger reagents are added; the resulting light emitted by the acridinium label is directly proportional to the concentration of intact PINP in the original sample.(Unpublished Mayo method)
