Description
Intended Uses: This immunoassay kit allows for the in vitro quantitative determination of bovine VIP peptides concentrations in serum, Plasma, tissue homogenates and Cell culture supernates and Other biological fluids.
Principle of the Assay: The microtiter plate provided in this kit has been pre-coated with an antibody specific to VIP peptides. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for VIP peptides and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain VIP peptides, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm. The concentration of VIP peptides in the samples is then determined by comparing the O.D. of the samples to the standard curve
