Kv3.1b/KCNC1 Blocking Peptide (#BLP-PC014) is the original antigen used for immunization during Anti-KV3.1b (KCNC1) Antibody (#APC-014) generation. The blocking peptide binds and ‘blocks’ Anti-Kv3.1b/KCNC1 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.
