SynDIG1 Blocking Peptide (#BLP-GC049) is the original antigen used for immunization during Anti-SynDIG1 Antibody (#AGC-049) generation. The blocking peptide binds and ‘blocks’ Anti-SynDIG1 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.
