Anti-ACTA2 Antibody [Assigned #A11111]

Rabbit monoclonal IgG antibody raised against ACTA2 (smooth muscle α-actin), supplied by Antibodies.com as an unconjugated reagent in a 200 µl vial. ACTA2 is a 42 kDa actin isoform expressed in vascular smooth muscle cells and myofibroblasts, and this reagent is validated for Western blot, immunohistochemistry, immunocytochemistry, immunofluorescence, and flow cytometry across human, mouse, and rat samples. Researchers use it to map smooth muscle differentiation, track tissue fibrosis progression, characterize wound healing responses, and profile tumor stromal remodeling, where α-SMA serves as a canonical marker of activated myofibroblasts and contractile smooth muscle lineages. For long-term stability, store the antibody at -20°C in working aliquots and limit freeze-thaw cycles to preserve binding performance.
