KCNC3/Kv3.3 Blocking Peptide (#BLP-PC102) is the original antigen used for immunization during Anti-KCNC3 (KV3.3) Antibody (#APC-102) generation. The blocking peptide binds and ‘blocks’ Anti-KCNC3/Kv3.3 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.
