B2 Bradykinin Receptor/BDKRB2 Blocking Peptide (#BLP-BR012) is the original antigen used for immunization during Anti-B2 Bradykinin Receptor (BDKRB2) Antibody (#ABR-012) generation. The blocking peptide binds and ‘blocks’ Anti-B2 Bradykinin Receptor/BDKRB2 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.
