KCNF1/Kv5.1 Blocking Peptide (#BLP-PC134) is the original antigen used for immunization during Anti-KCNF1 (KV5.1) Antibody (#APC-134) generation. The blocking peptide binds and ‘blocks’ Anti-KCNF1/Kv5.1 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.
