For other salt forms please inquire. Fluorescent analogue of GTP with λexc 408 nm and λem 552 nm, which can substitute for GTP in the interaction with various enzymes and proteins. It is sensitive to indicators of local environment such as polarity and viscosity, and frequently exhibits a spectral shift and fluorescence enhancement upon binding to a protein. Inhibitor of soluble guanylyl cyclase (sGC). Detailed technical information available. References: Hiratsuka, T., J. Biol. Chem., 260, 4784 - 4790 (1985); Suryanarayana et al., J. Pharmacol. Exp.
