Anti-Actin β Antibody

Beta-actin (encoded by ACTB) is a ~42 kDa cytoskeletal protein that participates in cell motility, cytoplasmic streaming, and maintenance of cell shape and polarity. Rabbit polyclonal antibodies raised against this conserved housekeeping protein serve as widely adopted loading controls in Western blot and as cytoskeletal markers in immunohistochemistry. This unconjugated preparation from Antibodies.com is validated for Western blot, immunohistochemistry, and ELISA, with cross-reactivity to human, mouse, and rat samples. Supplied as a 100 µl vial of polyclonal antiserum, it supports normalization of protein loading, studies of cytoskeletal remodeling in cancer and fibrosis models, and developmental biology research across multiple model organisms.
