Fluorescent GTP analogue
Cat. No.: B 166
CAS No.: [pending]
Shipping: Dry ice

For other salt forms or a guaranteed higher purity please inquire. Bis-ANT-GTP is an analogue of guanosine-5'-triphosphate, where both ribose hydroxyl groups have been modified with the relatively small fluorescent anthraniloyl group (λexc 373 nm, λem ~422 nm).


Vial containing 500 µl of 10 mM aqueous solution of pH 7.6.

The category "Future Products" lists structures that are already "in the pipeline" and nearly ready to be offered as regular products. Please just inquire, your interest will certainly accelerate the process.
