Kit Principle:
Aviva Systems Biology CD9 ELISA Kit (Human) (OKCD00751) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for CD9 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips). Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for CD9 is added, incubated and followed by washing. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration is read by absorbance at 450 nm and is quantitatively proportional to the amount of sample CD9captured in well.
