This assay is a two-site ELISA. The micro-plate is pre-coated with a monoclonal antibody against C-peptide. Standards and samples are added into the wells and co-incubated with a biotin labeled monoclonal antibody. After wash step to remove any unbound reagents, streptavidin-HRP conjugate (STP-HRP) is added. After the last wash step, TMB substrate is added and colour develops in proportion to the amount of C-peptide bound initially. The assay is stopped and the optical density of the wells determined using a micro-plate reader. Since the increases in absorbance are directly proportional to the amount of captured C-peptide, the unknown sample concentration can be interpolated from a reference curve included in each assay.
