SLC22A2 (OCT2) Blocking Peptide (#BLP-CT020) is the original antigen used for immunization during Anti-SLC22A2 (OCT2) Antibody (#ACT-020) generation. The blocking peptide binds and ‘blocks’ Anti-SLC22A2 (OCT2) 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.
