PrRP Receptor/GPR10 Blocking Peptide (#BLP-PR054) is the original antigen used for immunization during Anti-PrRP Receptor (GPR10) Antibody (#APR-054) generation. The blocking peptide binds and ‘blocks’ Anti-PrRP Receptor/GPR10 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.
