Actin, a highly conserved protein, is a major component of both the cytoskeletal and contractile structures in all cell types. It varies in amount, being related to the type of differentiation and to the functional state of cells and tissues. Actin can be found in two different forms of aggregation, the globular or the fibrillar state, and at least six distinct isoforms occur in vertebrates. The actins exhibit over 90% sequence homology, but each isoform has a unique NH2-terminal sequence.
The ACTA1 (actin, α 1) gene is mapped to human chromosome 1q42.13. The gene codes for actin 1, a thin filament component of skeletal muscle.
In immunoblotting, the product localizes actin in many species ranging from human skeletal muscle to amoeba. The product recognizes the 42 kDa actin band using immunoblotting techniques in human or animal tissue extracts.
Anti-Actin specifically stains typical stress fibers in cultured chicken fibroblasts.
The C-terminal actin fragment attached to Multiple Antigen Peptide (MAP) backbone.
May be used to study actin structure and function and to probe binding sites of actin-binding proteins.
Rabbit anti-actin antibody can be used for western blot assays. The antibody can also be used for immunohistochemistry (1:25, using human or animal tissue sections) and indirect immunofluorescence (1:40, using chicken fibroblasts) applications.
Used to study actin structure and function and to probe binding sites of actin-binding proteins. Protein lysates generated from embryonic mouse limb tissue was analyzed by western blot using actin as the loading control. Actin was detected using rabbit anti-actin at 1:8000. Actin detected by a rabbit anti-actin antibody was used as a loading control for MCF7 cell lysates. Actin was detected at 42 kDa.

Actin is a cytoskeletal protein that regulates cell motility, secretion, phagocytosis and cytokinesis. The NH2-terminal of actin may function as an antigen. This terminal may also modulate actin interactions and may associate with proteins such as myosin. Actin protein is essential for the formation of mature platelets.
Mutations in ACTA1 (actin, α 1) is known to cause thin filament myopathy such as nemaline myopathy, congenital myopathy, actin myopathy, intranuclear rod myopathy, cap myopathy and core myopathy. Upregulation of the gene is observed in orthotopic liver transplantation without any earlier evidence of autoimmune liver disease. The encoded protein actin forms a network of filaments and is responsible for the shape of the cell. It provides cellular strength and promotes active movement of the cell.
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide as preservative.
Storage and Stability
For continuous use, store at 2-8 °C for up to one month.
For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use.
