GABA Transporter 2/GAT-2 Blocking Peptide (#BLP-GT002) is the original antigen used for immunization during Anti-GABA Transporter 2 (GAT-2) Antibody (#AGT-002) generation. The blocking peptide binds and ‘blocks’ Anti-GABA Transporter 2/GAT-2 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.
