B1 Bradykinin Receptor/BDKRB1 Blocking Peptide (#BLP-BR011) is the original antigen used for immunization during Anti-B1 Bradykinin Receptor (BDKRB1) Antibody (#ABR-011) generation. The blocking peptide binds and ‘blocks’ Anti-B1 Bradykinin Receptor/BDKRB1 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.
