For other salt forms or a guaranteed higher purity please inquire. ATP-γ-AmNS is a fluorescent analogue of ATP with λem 460 nm (quantum yield = 0.63). Upon cleavage of the α-β-phosphoryl bond the emission maximum shifts to 475 nm. Detailed technical information available. References: Yarbrough, Biochem. Biophys. Res.
