CRMP1 Blocking Peptide (#BLP-IP028) is the original antigen used for immunization during Anti-CRMP1 Antibody (#AIP-028) generation. The blocking peptide binds and ‘blocks’ Anti-CRMP1 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.
