For other salt forms or higher purity please inquire. iso-GTP is an analogue of adenosine-5'-O-triphosphate (ATP) with an additional carbonyl group at position 2 of the nucleobase and of guanosine-5'-O-triphosphate (GTP), respectively, where the carbonyl group at position 6 and the amino group at position 2 have changed places. iso-GTP can be useful in receptor mapping studies. The corresponding diphosphate form is offered as well (isoGDP, Cat. No. I 038). Detailed technical information available. References: Lascu et al., Biochim. Biophys.
