KCC2/SLC12A5 Blocking Peptide (#BLP-KT005) is the original antigen used for immunization during Anti-KCC2 (SLC12A5) Antibody (#AKT-005) generation. The blocking peptide binds and ‘blocks’ Anti-KCC2/SLC12A5 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.
