General Notes
Mouse anti human actin alpha (smooth muscle) antibody, clone 1A4 recognises alpha smooth muscle actin. Actins are highly conserved proteins that play a role in cell contractile activity, motility, cytokinesis, and in maintaining cell structure. Alpha smooth muscle actin is expressed in vascular smooth muscle, myofibroblasts and myoepithelial cells and also in tumours derived from these cells.
