For other salt forms or higher purity please inquire. iso-GDP is an analogue of adenosine-5'-O-diphosphate (ADP) with an additional carbonyl group at position 2 of the nucleobase and of guanosine-5'-O-diphosphate (GDP), respectively, where the carbonyl group at position 6 and the amino group at position 2 have changed places. iso-GDP can be useful in receptor mapping studies. The corresponding triphosphate form is offered as well (isoGTP, Cat. No. I 039). Detailed technical information available. References: Barzu et al., Biochim. Biophys.
