Product Overview
This rabbit polyclonal antibody detects P2X purinoceptor 4 (gene P2RX4) in human samples and is validated for Western blot and ELISA. The predicted molecular weight is 43.4 kDa, and the supplier reports an observed band at about 70 kDa.
P2X4 (P2RX4) is an ATP-gated cation channel present on the cell surface and in lysosomes. It is highly expressed in immune cells and microglia, where it supports T-cell activation and microglial responses, and it is widely studied in neuropathic pain and neuroinflammation.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human) |
|---|---|
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human A549 cells, human HeLa cells, human SH-SY5Y cells, human MCF-7 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Recombinant human P2X4/P2RX4 fragment (Gln111–Glu249), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places P2X purinoceptor 4 in the cell membrane and lysosome membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
