Na+/H+ Exchanger 5/NHE-5 Blocking Peptide (#BLP-NX005) is the original antigen used for immunization during Anti-Na+/H+ Exchanger 5 (NHE-5) Antibody (#ANX-005) generation. The blocking peptide binds and ‘blocks’ Anti-Na+/H+ Exchanger 5/NHE-5 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.
