Nav1.5/SCN5A (1978-2016) Blocking Peptide (#BLP-SC013) is the original antigen used for immunization during Anti-NaV1.5 (SCN5A) (1978-2016) Antibody (#ASC-013) generation. The blocking peptide binds and ‘blocks’ Anti-Nav1.5/SCN5A (1978-2016) 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.
