ENaC β/SCNN1B (extracellular) Blocking Peptide (#BLP-SC019) is the original antigen used for immunization during Anti-ENaC β (SCNN1B) (extracellular) Antibody (#ASC-019) generation. The blocking peptide binds and ‘blocks’ Anti-ENaC β/SCNN1B (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.
