Mouse Anti-KCNN4 (KCa3.1, SK4) (extracellular) Antibody (#ALM-051) is a highly specific monoclonal antibody directed against an epitope of the human channel. The antibody can be used in western blot, immunocytochemistry, immunohistochemistry, and indirect flow cytometry applications. It has been designed to recognize KCNN4 from human, rat, and mouse samples._x005F Mouse Anti-KCNN4 (KCa3.1, SK4) (extracellular)-Biotin Antibody (#ALM-051-B) is directly labeled with biotin. Strepavidin tagged with HRP or with a fluorescent probe can then be used to detect the protein. The biotin/strepavidin system is ideal for minimizing cross-reactivity when same species antibodies are simultaneously used. Mouse Anti-KCNN4 (KCa3.1, SK4) (extracellular)-Biotin Antibody has been tested in direct flow cytometry and immunocytochemistry applications and is specially suited to experiments requiring simultaneous labeling of different markers.
