Description générale

Cet anticorps (également appelé anticorps anti-α-Sm-1) est spécifique de l'unique isoforme de l'α-actine du muscle lisse. Il réagit spécifiquement avec l'α-actine du muscle lisse lors de tests d'immunoblotting et marque les cellules de muscle lisse sur des coupes histologiques congelées ou fixées au formol et incluses en paraffine.
Actin is a highly conserved protein that 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 isoforms are comprised of three α actins (skeletal, cardiac, smooth), one β actin (β-non-muscle) and two γ actins (γ smooth muscle and γ non-muscle).

Immunogène

Décapeptide de synthèse N-terminal de l'α-actine du muscle lisse.

Application

Des coupes incluses en paraffine de greffons de tissus testiculaires de rat ont été colorées par immunohistochimie (IHC) à l'aide de l'anticorps monoclonal de souris anti-actine de muscle lisse.
Des tissus cardiaques de souris colorés au x-gal ont été analysés par IHC à l'aide de l'anticorps primaire monoclonal de souris anti-actine de muscle lisse afin d'identifier les myofibroblastes.
Une immunocytochimie a été réalisée sur des cellules de muscle lisse d'aortes de bovin à l'aide de l'anticorps monoclonal anti-ACTA2. Les cellules ont d'abord été cultivées sur des lamelles de verre, puis fixées dans 50 % d'acétone/EtOH pendant 10 minutes à 4 °C.

Immunohistochemistry (1 paper)
Immunocytochemistry was performed on kertocytes fixed in 1% PFA and incubated with mouse monoclonal anti-smooth muscle actin (14A) at a 1:100 dilution.
Mouse monoclonal anti-actin, α−smooth muscle-alkaline phosphatase antibody has been used for immunohistochemical application in mouse and human tissues.
