For other salt forms please inquire. Fluorescent analogue of guanosine-5’-diphosphate (λexc 350 nm; λem 442 nm), useful for research into GDP-dependent receptor proteins. The MANT fluorophore has a certain sensitivity for its environment and can change its spectral properties upon binding (compare: Hiratsuka, Biochim. Biophys. Acta, 742, 496 - 508 (1983)). Detailed technical information available. References: Wieden et al., J. Biol. Chem., 277, 6032 - 6036 (2002); Rehmann, Methods Enzymol., 407, 159 - 173 (2006).
