KCNS2/Kv9.2 Blocking Peptide (#BLP-PC132) is the original antigen used for immunization during Anti-KCNS2 (KV9.2) Antibody (#APC-132) generation. The blocking peptide binds and ‘blocks’ Anti-KCNS2/Kv9.2 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.
