Assay Methodology: Quantitative Sandwich ELISA

Aviva Systems Biology Il21 ELISA Kit (Mouse) (OKEH04088) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for Il21 has been pre-coated onto a 96-well plate (12 x 8 Well Strips) and blocked. Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for Il21 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 to generating a blue color product that changes to yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm is quantitatively proportional to the amount of sample Il21 captured in the well.

Mean Intra-assay CV%: <= 8.9% (n = 20)
Mean Inter-assay CV%: <= 11.5% (n = 20)
