Predicted Species Reactivity Rat
Kit Detection Method Colorimetric, OD450 nm
Kit Duration ~ 3 Hours
Kit Principle Aviva Systems Biology TNF ELISA Kit (Rat) (OKEH00223) is based on standard sandwich enzyme-linked immuno-sorbent assay technology. An antibody specific for TNF has been pre-coated onto a 96-wellplate (12 x 8 Well Strips) and blocked. Standards or test samples are added to the wells, incubated and removed. After washing,a biotinylated detector antibody specific for TNF 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 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 TNF captured in well.

Description of Target Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation.
