ZIP3/SLC39A3 Blocking Peptide (#BLP-ZT003) is the original antigen used for immunization during Anti-ZIP3 (SLC39A3) Antibody (#AZT-003) generation. The blocking peptide binds and ‘blocks’ Anti-ZIP3/SLC39A3 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.
