Glycine Receptor β Blocking Peptide (#BLP-GR014) is the original antigen used for immunization during Anti-Glycine Receptor β Antibody (#AGR-014) generation. The blocking peptide binds and ‘blocks’ Anti-Glycine Receptor β 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.
