    Product Description

    PPADS is a non-selective P2 purinergic antagonist that blocks recombinant P2X1-5 (IC50s = 1-2.6 μM), native P2Y2-like (IC50 = ~0.9 mM), and recombinant P2Y4 (IC50 = ~15 mM) receptors.1 PPADS antagonism of ATP-sensitive P2 receptors produces neuroprotective effects in an ischemia model with permanent middle cerebral artery occlusion in spontaneously hypertensive rats.2

    WARNING This product is not for human or veterinary use.
