GPR55 (extracellular) Blocking Peptide (#BLP-CR062) is the original antigen used for immunization during Anti-GPR55 (extracellular) Antibody (#ACR-062) generation. The blocking peptide binds and ‘blocks’ Anti-GPR55 (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.

- Expression of GPR55 in rat substantia nigra.Immunohistochemical staining of perfusion-fixed frozen rat brain sections with Anti-GPR55 (extracellular) Antibody (#ACR-062), followed by goat anti-rabbit-AlexaFluor-488. A. GPR55 immunoreactivity (green) appears in the substantia nigra pars compacta (SNC) in neurons (arrows). B. Pre-incubation of the antibody with GPR55 (extracellular) Blocking Peptide (BLP-CR062), suppressed staining. Cell nuclei are stained with DAPI (blue). SNR = substantia nigra pars reticulata.
