Mouse Kv1.7/KCNA7 Blocking Peptide (#BLP-PC063) is the original antigen used for immunization during Anti-Mouse KV1.7 (KCNA7) Antibody (#APC-063) generation. The blocking peptide binds and ‘blocks’ Anti-Mouse Kv1.7/KCNA7 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.
