Rat PP(Pancreatic Polypeptide) ELISA Kit

Competitive Inhibition

Enzyme & Kinase; Metabolic pathway; Tumor immunity; Gastroenterology

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Pepsin (PP) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Pepsin (PP) and unlabeled Pepsin (PP) (Standards or samples) with the pre-coated antibody specific to Pepsin (PP). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Pepsin (PP) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Pepsin (PP) in the sample.
