Cattle PSPB(Pregnancy Specific Protein B) ELISA Kit

Cattle PSPB(Pregnancy Specific Protein B) ELISA Kit is an ELK Biotechnology ELISA kit for research measurement of PSPB.

Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Cattle PSPB. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Cattle PSPB. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Cattle PSPB in the samples is then determined by comparing the OD of the samples to the standard curve.
