ENT3/SLC29A3 Blocking Peptide (#BLP-NT053) is the original antigen used for immunization during Anti-ENT3 (SLC29A3) Antibody (#ANT-053) generation. The blocking peptide binds and ‘blocks’ Anti-ENT3/SLC29A3 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.
