MCUR1/CCDC90A Blocking Peptide (#BLP-CC321) is the original antigen used for immunization during Anti-MCUR1 (CCDC90A) Antibody (#ACC-321) generation. The blocking peptide binds and ‘blocks’ Anti-MCUR1/CCDC90A 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.
