CGMP ELISA Kit

Cyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP) . cGMP acts as a second messenger much like cyclic AMP. Its most likely mechanism of action is activation of intracellular protein kinases in response to the binding of membrane-impermeable peptide hormones to the external cell surface. Guanylate cyclase (GC) catalyzes cGMP synthesis. This enzyme converts GTP to cGMP. In turn, peptide hormones such as the atrial natriuretic factor activate membrane-bound GC, while soluble GC is typically activated by nitric oxide to stimulate cGMP synthesis.

Aviva Systems Biology cGMP ELISA Kit (OKEH02546) is based on a competitive enzyme immunoassay technique. The microtiter well-plate in this kit has been pre-coated with an anti-cGMP antibody. Sample or standards are added to the wells along with a fixed quantity of biotinylated cGMP and incubated. The cGMP found in the sample or standards competes with the biotinylated cGMP for limited binding sites on the immobilized anti-cGMP antibody. Excess unbound biotinylated cGMP and sample or standard cGMP is washed from the plate. Avidin-HRP conjugate is added, incubated and washed. An enzymatic reaction is then produced through the addition of TMB substrate which is catalyzed by the immobilized HRP to generate a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration is measured by reading the absorbance at 450 nm which is quantitatively proportional to the amount of biotinylated cGMP captured in the well and inversely proportional to the amount of cGMP which was contained in the sample or standard.
