Description
Actins are highly conserved proteins ubiquitously expressed in all eukaryotic cells. They comprise, along with microtubules, a major component of the cytoskeleton. Actin has been found to be expressed in at least six isomeric forms. It is expressed in heart and skeletal striated muscle tissue, and in certain smooth muscle tissues, regulating contractile potentials for these cells. It is also expressed in the cytoplasm of non-muscle cells, functioning to control cell structure and motility (1). Polymerization of globular actin (G-actin) leads to a structural filament (F-actin), whose formation requires the Arp2/3 complex (2). It has been reported that actin is hyperphosphorylated in primary breast tumors (3). It has also been shown that actin dysfunction leads to certain types of heart failure (4). Smooth muscle alpha actin is of further interest because it is one of a few genes whose expression is relatively restricted to vascular smooth muscle cells. Furthermore, expression of smooth muscle alpha actin is regulated by hormones and cell proliferation, and is altered by pathological conditions including oncogenic transformation and atherosclerosis (5).

Products Data

A. Immunohistochemical analysis of paraffin-embedded human uterus tissue using anti-a-Actin (Smooth Muscle) RabMAb (cat. #1184-1); shows positive staining of smooth muscle tissue.
B. Immunohistochemical analysis of paraffin-embedded skeletal muscle tissue using anti-a-Actin (Smooth Muscle) RabMAb (cat. #1184-1); shows negative staining of skeletal muscle tissue.
C. Western blot analysis on A431 cell lysate using anti-a-Actin (Smooth Muscle) RabMAb (catalog #1184-1).

Specificity
A synthetic peptide corresponding to N-terminus of human Actin was used as immunogen. This antibody only detects actin in smooth muscle in immunohistochemistry.

Storage Condition and Buffer
Store at -20 °C. Buffer: 50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA. Stable for 12 months from date of receipt.

Alternative Names
ACTG2 antibody, ACT antibody, ACTA3 antibody, ACTE antibody, ACTL3 antibody, ACTSG antibody, Actin, gamma-enteric smooth muscle antibody, Alpha-actin-3 antibody, Gamma-2-actin antibody, Smooth muscle gamma-actin antibody
