SCN11A/Nav1.9 Blocking Peptide (#BLP-SC017) is the original antigen used for immunization during Anti-SCN11A (NaV1.9) Antibody (#ASC-017) generation. The blocking peptide binds and ‘blocks’ Anti-SCN11A/Nav1.9 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.
