BzATP triethylammonium salt is a potent agonist for multiple P2X receptor subtypes (P2X1, P2X2, P2X3, P2X2/3, P2X4, P2X7). It is widely used in neuroscience and immunology research to study purinergic signaling, where it can induce cellular responses such as cell death and modulate synaptic transmission in both in vitro and in vivo models.
