Anti-β-actin Antibody

β-actin is one of the most widely used loading controls in cell biology and biochemistry research, appearing at approximately 42 kDa across many species. This unconjugated mouse monoclonal reagent from Antibodies.com is raised against β-actin and validated for Western blot, immunohistochemistry, and immunofluorescence workflows. It detects the target in human, rat, mouse, monkey, canine, and chicken samples, making it broadly useful for cross-species studies in academic and industrial labs. The antibody is supplied as 100 µl of liquid, suitable for multiple blotting and staining experiments when used at standard dilutions. Storage at 4 °C is recommended for short-term use, with aliquots kept at -20 °C for longer-term stability. Researchers commonly deploy this clone to confirm equal protein loading, normalize signal across lanes, or visualize cytoskeletal architecture in fixed cells and tissue sections.
