Product Specifications
Immunogen
N-Terminal decapeptide of alpha smooth muscle isoform of actin and conjugated to KLH. (Uniprot: P62736)
Localization
Cytoplasmic
Specificity
Actin is a major component of the cytoskeleton and is present in most cell types. This monoclonal antibody is highly specific to actin from smooth muscles. Its epitope lies in the first four N-terminal amino acids. This monoclonal antibody does not stain cardiac or skeletal muscle; however, it does stain myofibroblasts and myoepithelial cells. 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 specific actin and anti-smooth muscle actin and are negative with anti-myogenin.

Background: alpha-Smooth Muscle Actin
ACTA2 encodes alpha Smooth Muscle Actin and is also known as alpha-actin, alpha-actin-2, aortic smooth muscle or alpha smooth muscle actin (alpha-SMA, SMactin, alpha-SM-actin, ASMA). Alpha Smooth Muscle Actin is frequently used as a marker of smooth muscle differentiation and has a theoretical molecular weight of 42 kDa. Smooth muscle alpha actin is one of a few genes whose expression is predominantly expressed in vascular smooth muscle cells that is used to study myofibroblasts and fibrosis (1). Excessive accumulation of alpha smooth muscle actin-positive (ACTA2+) activated myofibroblasts is observed in Idiopathic pulmonary fibrosis (2). Expression of smooth muscle alpha actin is regulated by cell proliferation and is altered in pathological conditions including atherosclerosis and is common in metastatic cancers (1,3).
