cGMP ELISA kits are assays designed to detect cyclic guanosine monophosphate (cGMP), a derivative of guanosine triphosphate. This molecule plays a role as a secondary messenger for cellular signaling pathways and can regulate apoptosis and glycogenolysis. It can relax smooth muscles, which can cause vasodilation and increase blood flow. cGMP interacts with kinases such as protein kinase G (PKG) and can indirectly alter NO levels in cells.
