BioVision’s human DPP IV (Dipeptidyl peptidase-4) or CD26 (cluster of differentiation 26) ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human CD26. This assay employs an antibody specific for CD26 coated on a 96-well plate. Standards and samples are pipetted into the wells and CD26 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-human CD26 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of CD26 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm. The minimum detectable dose of CD26 is typically less than 25 pg/ml. Detection Range: 25 pg/ml – 8,000 pg/ml. The intra-Assay reproducibility is CV<10% & inter-Assay is CV<12%.
