Drug Names

Generic Name：Sheep Pregnancy Associated Plasma Protein B (PAPPB) ELISA Kit

Purpose

Our Sheep Pregnancy Associated Plasma Protein B (PAPPB) ELISA kit is to assay PAPPB levels in Sheep serum, plasma, culture media or any biological fluid.

Principle

This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate provided in this kit has been pre-coated with an antibody specific to PAPPB, Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)-conjugated antibody specific for PAPPB is added to each Microelisa stripplate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain PAPPB and HRP conjugated PAPPB antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm. The OD value is proportional to the concentration of PAPPB. You can calculate the concentration of PAPPB in the samples by comparing the OD of the samples to the standard curve.
