4-Thiouridine 5′-triphosphate (tetrasodium)

4-Thiouridine 5′-triphosphate (4-Thio-UTP) tetrasodium is a potent P2Y2 and P2Y4 receptor agonist, with EC50s of 35 and 350 nM for hP2Y2 and hP2Y4, respectively. 4-Thiouridine 5′-triphosphate tetrasodium can be used in the study of crosslinking experiments, labeling of transcriptional complex[1][2].
