c-di-AMP diammonium is a STING agonist that binds to the transmembrane protein STING, activating the TBK3-IRF3 signaling pathway and subsequently triggering the production of type I IFN and TNF. It also functions as a bacterial second messenger, regulating cell growth, survival, and virulence primarily in Gram-positive bacteria, and modulating the host immune response. Furthermore, c-di-AMP diammonium acts as a potent mucosal adjuvant, stimulating both humoral and cellular immune responses.

Medchemexpress LLC Procion blue HB | 12236-82-7 | 97.93% | 5 MG

Procion Blue HB (Reactive Blue 2) is a purinergic antagonist intended for research use only. It acts as an ATP receptor antagonist and induces Ca2+ oscillations in HeLa cells.

Enhances a Ca2+ response to histamine linked to the PLC cascade.
May activate the PLC cascade in an extracellular Ca2+-dependent manner, inducing Ca2+ oscillations.
Increases K+ secretion in a dose-dependent manner in rat cochlea strial marginal cells.
Exhibits antagonistic activities at P2Y4, with potency correlating to K+ secretion.
Potent inhibitor of a protein kinase isolated from thylakoids, with noncompetitive inhibition (Ki of 8 μM for membrane-bound kinase, 6 μM for purified kinase).
Selectively inhibits responses mediated via the P2y-purinoceptor within a limited concentration range.
Blocks ATP-induced oscillation at concentrations of 0.3-10 μM in a concentration-dependent manner.
