SLC28A3/CNT3 (extracellular) Blocking Peptide (#BLP-NT063) is the original antigen used for immunization during Anti-SLC28A3/CNT3 (extracellular) Antibody (#ANT-063) generation. The blocking peptide binds and ‘blocks’ Anti-SLC28A3/CNT3 (extracellular) 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.
