Prostaglandin F2-α Receptor/PTGFR Blocking Peptide (#BLP-PR067) is the original antigen used for immunization during Anti-Prostaglandin F2-α Receptor/PTGFR Antibody (#APR-067) generation. The blocking peptide binds and ‘blocks’ Anti-Prostaglandin F2-α Receptor/PTGFR 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.

- Expression of Prostaglandin F2-alpha receptor in mouse hippocampusImmunohistochemical staining of perfusion-fixed frozen mouse brain sections with Anti-Prostaglandin F2-α Receptor/PTGFR Antibody (#APR-067) (1:200), followed by goat anti-rabbit-AlexaFluor-488. PTGFR staining (green) in mouse hippocampal dentate gyrus is detected in cell bodies (arrows). Cell nuclei are stained with DAPI (blue). Mouse brain hippocampal dentate gyrus sections were obtained two hours following kainate acid intraventricular injection.
