Widely used in cell culture and biological research to modulate cellular signaling pathways. Acts as a second messenger in many hormonal and neurotransmitter actions, particularly in studies involving protein kinase A activation. Commonly applied in studies of metabolism, gene expression, and cell differentiation. Frequently used in research on cardiac function, where it helps investigate heart muscle contraction and regulation. Also utilized in neuroscience to examine synaptic transmission and neuronal plasticity. Its stable salt form enhances solubility and bioavailability in aqueous solutions, making it suitable for in vitro and in vivo experiments. Employed in diagnostic assays and drug development platforms targeting G-protein coupled receptors and cyclic AMP-dependent pathways.
