KCNH2/HERG Blocking Peptide (#BLP-PC062) is the original antigen used for immunization during Anti-KCNH2 (HERG) Antibody (#APC-062) generation. The blocking peptide binds and ‘blocks’ Anti-KCNH2/HERG 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.
