A prototypic P2X7 purinergic receptor agonist that exhibits about 3-fold higher agonistic potency for induction of nucleotide channels than ATP (EC50 = 15uM vs 50uM). Serves as a photo-affinity analog of ATP. Its agonistic activity is significantly reduced in the presence of serum albumin. Can serve as a substrate analog for submitochondrial particle ATPase activity (Km = 940uM). Induces a dose-dependent decrease in wild-type murine neural progenitor cell viability and an increase in caspase-3 activity. These effects are not observed in P2X7-/- mice.
Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
