X-ray analysis[1, 2]
Hydrolyse studies[3, 4]Agonistic ligand, mainly for nucleoside receptor A1
Nucleosidephosphates stabilized against hydrolytic degradation can directly bind to nucleoside receptors.

Specific Ligands:

Thymidylate kinase[1, 2]

for P2Y2 receptor[5]

Please note: For reasons of stability, please make sure that the pH value of a solution of this product never drops below 7.0. This can be achieved by dissolving the nucleotide in a buffer of your choice (50 - 100 mM, pH 7 - 10). Dissolve and adjust concentration photometrically.
When stored at -20 °C, product may hydrolyze, thereby forming AppNH2 at a rate of up to 1 % per month!
