Measurement of intracellular cgmp levels
WebThus, there remains considerable interest in the measurement of intracellular cAMP concentrations in tissues and cell culture. cGMP is typically present at levels 10 to 100 fold lower than cAMP in most tissues and is formed by the action of the enzyme guanylate cyclase on GTP. WebCyclic guanosine monophosphate (cGMP) is a cyclic nucleotide derived from guanosine triphosphate (GTP). cGMP acts as a second messenger much like cyclic AMP. Its most …
