Na+/H+ Exchanger 7 (NHE7) (extracellular) Blocking Peptide (#BLP-NX007) is the original antigen used for immunization during Anti-Na+/H+ Exchanger 7 (NHE7) (extracellular) Antibody (#ANX-007) generation. The blocking peptide binds and ‘blocks’ Anti-Na+/H+ Exchanger 7 (NHE7) (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.
