P2X7 Receptor (extracellular) Blocking Peptide (#BLP-PR008) is the original antigen used for immunization during Anti-P2X7 Receptor (extracellular) Antibody (#APR-008) generation. The blocking peptide binds and ‘blocks’ Anti-P2X7 Receptor (extracellular) primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.
- Western blot analysis of rat brain membranes (lanes 1 and 5) and human K562 chronic myelogenous leukemia cell line (lanes 2 and 6) and Mouse WEHI-231 B cell lymphoma (lanes 3 and 7) and human HL-60 promyelocytic leukemia cell line (lanes 4 and 8):
- Expression of P2RX7 in rat pancreasImmunohistochemical staining of rat pancreas frozen section using Anti-P2X7 Receptor (extracellular) Antibody (#APR-008), (1:100), followed by mouse anti-rabbit-AlexaFluor-594 secondary antibody (red). Staining is present in endocrine cells of the Isle of Langerhans. Hoechst 33342 is used as the counterstain.
