Product Description
Specificity / Sensitivity
The immunoreactivity of this kit was tested against the following: ADP, AMP, ATP, cAMP, cGMP, cIMP, cTMP, CTP, GDP, GMP, and GTP. Relatively minor cross-reactivity was observed with cGMP and cIMP, with 10 fold higher sensitivity for cAMP compared to either cGMP or cIMP. No cross-reactivity was observed with any of the other factors tested. Kit sensitivity, as shown in Figure 1, demonstrates a dynamic range of 0.2 to 12 nM of cAMP. Changes in cellular cAMP levels following specific treatment with forskolin is shown in Figure 2 (CHO cells).

Background
Cyclic adenosine 3’,5’-monophosphate (cAMP) is an important second messenger involved in many signal transduction pathways in different cell types of numerous species (1-3). In mammalian cells, this important molecule is produced by adenylyl cyclases (AC). Extracellular stimuli such as neurotransmitters, hormones, chemokines, lipid mediators, and drugs can modulate AC activity to increase or decrease cAMP production by binding to a large number of transmembrane G protein-coupled receptors (4). The degradation of cAMP to AMP is catalyzed by phosphodiesterases that are regulated by intracellular nucleotide concentrations, phosphorylation, or binding of Ca2+/calmodulin and other regulatory proteins (5). A set of diverse molecules, including cAMP-dependent protein kinase (PKA), cyclic nucleotide-gated ion channels, and exchange proteins that are activated by cAMP (EPAC), mediate downstream cAMP signaling (6,7). cAMP modulates various biological processes including metabolism, differentiation, cardiac cell functions, neuronal signaling, cell adhesion, and immune functions (5-7).
