For other salt forms or a guaranteed higher purity please inquire. 3'-NH₂-GTP is an analogue of guanosine-5'-triphosphate, where the ribose 3' hydroxy group has been replaced by an amino group, which allows for conjugation with amine-reactive ligands to yield e.g. fluorescent or immobilized products.
