Actin, alpha, Smooth Muscle (BSA, Glycerol & Azide Free) (AP)

Recognizes the alpha-smooth muscle isoform of actin. Stains smooth muscle cells in vessel walls, gut walls, and myometrium. Myoepithelial cells in breat and salivary gland are also stained. Reacts with tumors arising from smooth muscles and myoepithelial cells. Does not crossreact with actin from fibroblasts (b-and g-cytoplasmic), striated muscle (a-sarcomeric), and myocardium (a-myocardial). Species Crossreactivity: Human, baboon, bovine, rabbit, mouse, rat and chicken.
