Anti-P2X4 Receptor (extracellular) Antibody (#APR-024) is a highly specific antibody directed against an extracellular epitope of the rat protein. The antibody can be used in western blot, immunocytochemistry and live cell flow cytometry applications. The antibody recognizes an extracellular epitope and can be used to detect the protein in living cells. It has been designed to recognize P2X4 from human, mouse, and rat samples._x005F Anti-P2X4 Receptor (extracellular)-PE Antibody (#APR-024-PE) is directly conjugated to the Phycoerythrin (PE) fluorophore. This conjugated antibody has been developed to be used in immunofluorescent applications such as direct flow cytometry and live cell imaging.
