2', 3'- O- (Bis- [5- bromoanthraniloyl])inosine- 5'- O- triphosphate ( Bis-Br-ANT-ITP )
Fluorescent ITP analogue
Cat. No.: B 119
CAS No.: [1350460-92-2]
Shipping: Dry ice

For other salt forms or a guaranteed higher purity please inquire. Analogue of inosine-5'-triphosphate with only moderate intrinsic fluorescence (λexc 350 nm, λem ~450 nm). The fluorophore has a certain sensitivity for its environment and is supposed to change its spectral properties upon binding. Useful for research into purine triphosphate-dependent receptor proteins.


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