EAAT3/EAAC1 Blocking Peptide (#BLP-GC023) is the original antigen used for immunization during Anti-EAAT3 (EAAC1) Antibody (#AGC-023) generation. The blocking peptide binds and ‘blocks’ Anti-EAAT3/EAAC1 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.
