This ELISA kit applies to the in vitro quantitative determination of Porcine VIP concentrations in serum, plasma and other biological fluids.This ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with VIP. During the reaction, VIP in the sample or standard competes with a fixed amount of VIP on the solid phase supporter for sites on the Biotinylated Detection Ab specific to VIP. Excess conjugate and unbound sample or standard are washed
