    Product Description

    Sp-Adenosine-5'-O-(1-thiotriphosphate) (Sp-ATP-α-S) is an isomer of the sulfur-containing nucleotide derivative ATP-α-S and an agonist of the purinergic P2Y1 receptor.1 It increases calcium mobilization in HEK293 cells expressing the P2Y1 receptor (EC50 = 9.4 nM for the human receptor). Sp-ATP-α-S inhibits ADP-induced aggregation of isolated human platelets (Ki = 4 μM).2 It induces relaxation of carbamoylcholine-preconstricted guinea pig taenia coli (EC50 = 426 nM).3

    WARNING This product is not for human or veterinary use.
