PACSIN1 Blocking Peptide (#BLP-IP023) is the original antigen used for immunization during Anti-PACSIN1 Antibody (#AIP-023) generation. The blocking peptide binds and ‘blocks’ Anti-PACSIN1 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.
