MANT-GTP
mant-gtp
A mixture of 2'-<em>O</em>-(<em>N</em>-methylanthraniloyl)guanosine triphosphate (2'-MANT-GTP; R1 = <em>N</em>-methylanthraniloyl and R2 = H) and 3'-<em>O</em>-(<em>N</em>-methylanthraniloyl)gluanosine triphosphate ((3'-MANT-GTP; R1 = H and R2 = <em>N</em>-methylanthraniloyl). At neutral pH, the isomers are in equilibrium. Used as a fluorescent guanine nucleotide analogue, particularly for kinetic analysis of enzymes and signaling  proteins.
