Anti-SCN4B (NaVβ4) (extracellular) Antibody (#ASC-044) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunocytochemistry, and immunohistochemistry applications. The antibody recognizes an extracellular epitope and is thus ideal for detecting NaVβ4 in living cells. It has been designed to recognize NaVβ4 from rat, human, and mouse samples.
