SCN2B/Navβ2 Blocking Peptide (#BLP-SC007) is the original antigen used for immunization during Anti-SCN2B (NaVβ2) Antibody (#ASC-007) generation. The blocking peptide binds and ‘blocks’ Anti-SCN2B/Navβ2 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.
