NKCC1/SLC12A2 Blocking Peptide (#BLP-NT071) is the original antigen used for immunization during Anti-NKCC1 (SLC12A2) Antibody (#ANT-071) generation. The blocking peptide binds and ‘blocks’ Anti-NKCC1/SLC12A2 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.
