Kit Description

GenScript cAMP ELISA Detection Kit is a competition enzyme-linked immunoassay which can be used for quantitative detection of cAMP (Adenosine 3',5'-cyclic monophosphate) in samples such as serum, plasma, saliva, cell culture supernatant, and urine. cAMP is an important secondary messenger in signal transduction pathways that follows a number of extracellular signals. cAMP activates or inhibits various enzymes by promoting their phosphorylation or dephosphorylation. Its concentration is converted from adenosine triphosphate (ATP) via adenylyl cyclases (AC), and is inactivated by hydrolysis to 5'-AMP by the actions of phosphodiesterases.

The anti-IgG Capture Plate is pre-coated with a fixed amount of Goat anti-mouse IgG to capture Mouse Anti-cAMP Monoclonal Antibody. When free cAMP or specimen and HRP-cAMP are added to the well, they compete in the solution to interact with the cAMP antibody captured on the plate. Other unbound molecules are removed by the wash step. The cAMP-HRP reacts with TMB substrate to develop a blue product in the solution. The reaction is stopped by adding stop solution and the color turns yellow which can be read at 450 nm by a Microtiter plate reader. Using the standard curve, the cAMP amount present in the unknown samples can be calculated by transforming its absorbance value.
