Kir4.1/KCNJ10 Blocking Peptide (#BLP-PC035) is the original antigen used for immunization during Anti-Kir4.1 (KCNJ10) Antibody (#APC-035) generation. The blocking peptide binds and ‘blocks’ Anti-Kir4.1/KCNJ10 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.
