Anti-P2RX4 Antibody

Raised in rabbit against the human P2X4 purinergic receptor, this unconjugated polyclonal reagent binds the ATP-gated cation channel encoded by the P2RX4 gene. The 100 µl vial supplies enough material for repeated western blot and immunofluorescence work on human samples. P2X4 channels are widely studied in macrophage and microglial biology, where ATP-evoked calcium influx drives neuropathic pain and inflammatory signaling. Storage at -20 °C in single-use aliquots preserves binding activity and avoids repeated freeze-thaw cycles that degrade antibody preparations. The unconjugated format lets laboratories pair this Antibodies.com reagent with custom fluorophores, biotin, or HRP for immunofluorescence detection of P2X4 in fixed cells and tissue sections. Validated for human reactivity, the antibody supports studies of neuroimmune signaling, ATP release mechanisms, and channelopathies where P2RX4 expression is altered.
