The monkey IL-2 ELISAPRO kit provides all necessary reagents and solutions required to quantify monkey IL-2 in solution, e.g. in cell culture supernatant, and serum/plasma samples. The kit contains ELISA plates pre-coated with monoclonal capture antibodies, biotinylated detection antibody, Streptavidin-HRP, TMB substrate, ELISA standard and ELISA diluent. The ELISA diluent prevents false positive read-outs which may be caused by heterophilic antibodies found in serum and plasma samples. React with human IL-2 and cross-react with IL-2 from non-human primates. The ELISA standard supplied is recombinant human IL-2. Range: 3.16-316 pg/ml
