An enzyme immunoassay for the quantitative measurement of active renin in serum and EDTA plasma. This product is for Research Use Only; International customers contact your representative to receive information about the CE marked version. The DRG Renin ELISA Kit is a solid phase enzyme-linked immunosorbent assay (ELISA) based on the sandwich principle. The microtiter wells are coated with a monoclonal [mouse] antibody directed towards a unique antigenic site of the human active Renin molecule. An aliquot of patient sample containing endogenous Renin is incubated in the coated well together with Assay Buffer. After incubation, unbound components are washed off. Finally, Enzyme Conjugate, which is a monoclonal anti-Renin antibody conjugated with horseradish peroxidase, is added, and after incubation, unbound enzyme conjugate is washed off. The amount of bound peroxidase is proportional to the concentration of Renin in the sample. Having added the substrate solution, the intensity of colour developed is proportional to the concentration of active Renin in the patient sample.
