Quanticon™ Rat IP-10/CXCL10(Interferon Gamma Induced Protein 10kDa)ELISA Kit

This kit uses the Sandwich-ELISA principle. The microtiter plate strips has been pre-coated with an affinity purified antibody to Rat IP-10/CXCL10. Standards or samples containing Rat IP-10/CXCL10 are added to the plate and reacted with capture antibody. A second anti-Rat IP-10/CXCL10 antibody labeled biotin is then added and binds to Rat IP-10/CXCL10 captured on the plate. After that, Streptavidin-Horseradish Peroxidase(SA-HRP) is added to form a sandwich complex of solid phase antibody-Rat IP-10/CXCL10-biotin labelled antibody-SA-HRP. And then, TMB substrate solution is added to all wells and incubated. An enzyme-catalyzed reaction generates a blue color in the solution, thereafter, stop solution is added to stop the substrate reaction and the color turns yellow. The yellow solution is read at a wavelength of 450nm. The concentration of Rat IP-10/CXCL10 in the samples is then calculated from the OD value by establishing a standard curve.
