Competitive Inhibition

Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Carbohydrate Antigen 19-5 (CA19-5) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Carbohydrate Antigen 19-5 (CA19-5) and unlabeled Carbohydrate Antigen 19-5 (CA19-5) (Standards or samples) with the pre-coated antibody specific to Carbohydrate Antigen 19-5 (CA19-5). 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 Carbohydrate Antigen 19-5 (CA19-5) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Carbohydrate Antigen 19-5 (CA19-5) in the sample.
