ZnT3/SLC30A3 Blocking Peptide (#BLP-ZT013) is the original antigen used for immunization during Anti-ZnT3 (SLC30A3) Antibody (#AZT-013) generation. The blocking peptide binds and ‘blocks’ Anti-ZnT3/SLC30A3 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.
