VGLUT1 Blocking Peptide (#BLP-GC035) is the original antigen used for immunization during Anti-VGLUT1 Antibody (#AGC-035) generation. The blocking peptide binds and ‘blocks’ Anti-VGLUT1 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.
