Description
Description: The kit is a sandwich enzyme immunoassay for in vitro quantitative measurement of PLAP/ALPP in Porcine serum, plasma and other biological fluids
Principle of the Assay: This ELISA kit uses Sandwich-ELISA as the method. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Porcine PLAP/ALPP. Standards or samples are added to the appropriate micro ELISA plate wells and bound by the specific antibody. Then a biotinylated detection antibody specific for Porcine PLAP/ALPP and Avidin-Horseradish Peroxidase (HRP) conjugate is added to each micro plate well successively and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Porcine PLAP/ALPP, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm. The OD value is proportional to the concentration of Porcine PLAP/ALPP. You can calculate the concentration of Porcine PLAP/ALPP in the samples by comparing the OD of the samples to the standard curve
