PPADS tetrasodium salt
Cat. No. 0625
Chemical Name: Pyridoxalphosphate-6-azophenyl-2',4'-
Biological ActivityA non-selective P2 purinergic antagonist. Blocks recombinant P2X1, P2X2, P2X3, P2X5 (IC50 = 1 - 2.6 μM), native P2Y2-like (IC50 ~ 0.9 mM), and recombinant P2Y4 (IC50 ~ 15 mM) receptors. Delays onset of calcium responses to mild hypoosmotic stress in cortical slices. iso-PPADS (Cat. No. 0683) also available.
