Rat SLC4A5/NBC4 Blocking Peptide (#BLP-NT076) is the original antigen used for immunization during Anti-Rat SLC4A5 (NBC4) Antibody (#ANT-076) generation. The blocking peptide binds and ‘blocks’ Anti-Rat SLC4A5/NBC4 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.
