The C-terminal actin fragment (C11 peptide, Ser-Gly-Pro-Ser-Ile-Val-His-Arg-Lys-Cys-Phe) attached to Multiple Antigen Peptide (MAP) backbone).

General description

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.
Anti-Actin specifically stains stress fibers in cultured chicken fibroblasts using indirect immunofluorescence and specifically localizes actin by immunoperoxidase labeling of formalin-fixed, paraffin embedded human or animal tissues. 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.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide as preservative.


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.
