Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

α-Smooth Muscle Actin Antibody recognizes endogenous levels of total α-smooth muscle actin protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human α-smooth muscle actin protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from various tissue using α-Smooth Muscle Actin Antibody (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). As expected, α-skeletal muscle extracts are negative for smooth muscle actin.


Actin proteins are major components of the eukaryotic cytoskeleton. At least six vertebrate actin isoforms have been identified. The cytoplasmic β- and γ-actin proteins are referred to as “non-muscle” actin proteins as they are predominantly expressed in non-muscle cells where they control cell structure and motility (1). The α-cardiac and α-skeletal actin proteins are expressed in striated cardiac and skeletal muscles, respectively. The smooth muscle α-actin and γ-actin proteins are found primarily in vascular smooth muscle and enteric smooth muscle, respectively. The α-smooth muscle actin (ACTA2) is also known as aortic smooth muscle actin. These actin isoforms regulate the contractile potential of muscle cells (1).
