2'- O- Benzyl- 3'- O- (N'- methylanthraniloyl)guanosine- 5'- O- triphosphate ( 2'-O-Bn-3'-MANT-GTP )
Ribose-modified fluorescent GTP analogue
Cat. No.: B 187
CAS No.: [pending]
Shipping: Dry ice

For other salt forms or a guaranteed higher purity please inquire. 2'-O-Bn-3'-MANT-GTP is a fluorescent (λexc 350 nm; λem 442 nm) analogue of GTP where the ribose hydroxy groups hav been modified by an ether bond to a benzyl group and an ester bond to a fluorescent MANT group, respectively.
