Nav1.7/SCN9A Blocking Peptide (#BLP-SC008) is the original antigen used for immunization during Anti-NaV1.7 (SCN9A) Antibody (#ASC-008) generation. The blocking peptide binds and ‘blocks’ Anti-Nav1.7/SCN9A 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.
