GPRC5B Blocking Peptide (#BLP-GR072) is the original antigen used for immunization during Anti-GPRC5B Antibody (#AGR-072) generation. The blocking peptide binds and ‘blocks’ Anti-GPRC5B 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.
