KCNC4/Kv3.4 Blocking Peptide (#BLP-PC019) is the original antigen used for immunization during Anti-KCNC4 (KV3.4) Antibody (#APC-019) generation. The blocking peptide binds and ‘blocks’ Anti-KCNC4/Kv3.4 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.
