The antibody (also known as anti-alpha-Sm-1) is specific for the single isoform of alpha-smooth muscle actin. It reacts specifically with alpha-smooth muscle actin in immunoblotting assays and labels smooth muscle cells in frozen or formalin-fixed, paraffin-embedded tissue sections.
Synonyms: Monoclonal Anti-Actin, alpha-Smooth Muscle; Acta2 Antibody; Alpha Smooth Muscle Actin Antibody Sigma; SMA Antibody - Anti-Actin, alpha-Smooth Muscle antibody, Mouse monoclonal; Sma Antibody; SMA
Storage: -20C
Application: Paraffin embedded sections of rat testis tissue grafts were immunohistochemically stained with mouse monoclonal anti-smooth muscle actin. IHC analysis of x-gal stained muouse cardiac tissue was performed using the primary antibody, mouse monoclonal anti-smooth muscle actin to identify myofibroblasts.
Biochem Physiol Actions: Actin and myosin are constituents of many cells types and are involved in a myriad of cellular processes including locomotion, cytokinesis, secretion, cytoplasmic streaming and phagocytosis. It has been shown that the relative proportion of actin isoforms are different in smooth muscles of different organs and change within the same population of smooth muscle cells during development, pathological situations and different culture conditions. The actin in cells of various species and tissue origin are very similar in their immunological and physical properties.
