Fluorescent Dyes  >  Fluorescently Labeled Nucleotides  >>  Mant-GTP [2'-/3'-O-(N'-Methylanthraniloyl)guanosine-5'-O-triphosphate, trisodium salt], 5mM in TE buffer(pH7.6)

Mant-GTP is a fluorescent analog of GTP with Ex/Em = 355/448 nm. The fluorescence quantum yield of Mant fluorophore is 0.2 in water which increases significantly in nonpolar solvents or upon binding to most proteins. This highly environmental sensitive fluorescence of Mant makes Mant-GTP useful for directly detecting the nucleotide-protein interactions.
