ZnT4 (SLC30A4) Blocking Peptide (#BLP-ZT014) is the original antigen used for immunization during Anti-ZnT4 (SLC30A4) Antibody (#AZT-014) generation. The blocking peptide binds and ‘blocks’ Anti-ZnT4 (SLC30A4) 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.
