For other salt forms please inquire. Fluorescent analogue of the metazoan cyclic dinucleotide second messenger and STING activator c[G(2',5')pA(3',5')p] (aka cGAMP(2'-5') or 2'3'-cGAMP, Cat. No. C 161). The MANT fluorophore (λexc 355 nm; λem 448 nm) has a certain sensitivity for its environment and can change its spectral properties upon binding. Compare: Hiratsuka, Biochim. Biophys. Acta, 742, 496 - 503 (1983). Detailed technical information available.
