Principle of Assay
Monkey I-FABP ELISA Kit (A327075) employs the sandwich enzyme immunoassay technique for the quantitative measurement of monkey I-FABP in serum, plasma, and other biological fluids. An antibody specific for I-FABP has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the I-FABP present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-I-FABP Antibody, which binds the captured I-FABP present in each well. Following incubation, unbound biotinylated detection antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is proportional to the amount of I-FABP captured in each well. The concentration of I-FABP can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
