KCNG1/Kv6.1 (extracellular) Blocking Peptide (#BLP-PC135) is the original antigen used for immunization during Anti-KCNG1 (KV6.1) (extracellular) Antibody (#APC-135) generation. The blocking peptide binds and ‘blocks’ Anti-KCNG1/Kv6.1 (extracellular) 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.
