Actin Antibody (smooth muscle)

Actin is a major component of the cytoskeleton and is present in most cell types. It is highly specific to actin from smooth muscles. <strong>This MAb does not stain cardiac or skeletal muscle; however, it does stain myofibroblasts and myoepithelial cells.</strong> This antibody could be used together with anti-muscle specific actin and myogenin in making a diagnosis of smooth muscle and skeletal muscle tumors. In most cases of rhabdomyosarcoma, this antibody yields negative results whereas anti-muscle specific actin and myogenin are positive. Leiomyosarcomas are positive only with anti-muscle...
