Pan VDAC Blocking Peptide (#BLP-VC001) is the original antigen used for immunization during Anti-VDAC Antibody (#AVC-001) generation. The blocking peptide binds and ‘blocks’ Anti-Pan VDAC 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.
