Alpha-Synuclein Blocking Peptide (#BLP-PZ035) is the original antigen used for immunization during Anti-Alpha-Synuclein Antibody (#APZ-035) generation. The blocking peptide binds and ‘blocks’ Anti-Alpha-Synuclein 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.
