Kv6.4 (KCNG4) Blocking Peptide (#BLP-PC138) is the original antigen used for immunization during Anti-Kv6.4 (KCNG4) Antibody (#APC-138) generation. The blocking peptide binds and ‘blocks’ Anti-Kv6.4 (KCNG4) 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.
