Descripción general

El anticuerpo (también conocido como anti-α-Sm-1) es específico para la isoforma α-actina de músculo liso. Reacciona de manera específica con la α-actina del músculo liso en análisis de inmunotransferencia y marca las células del músculo liso en cortes de tejido incluidas en parafina congeladas o fijadas con formalina.
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).

Inmunógeno

Decapéptido N-terminal sintético de la α-actina de músculo liso.

Aplicación

Se realizó inmunocitoquímica en células de músculo liso de aortas bovinas utilizando el anticuerpo monoclonal anti-ACTA2. Las células se cultivaron primero en cubreobjetos de vidrio y se fijaron en acetona al 50%/EtOH durante 10 minutos a 4 grados.
Se tiñeron inmunohistoquímicamente cortes incluidos en parafina de injertos de tejido testicular de rata con anticuerpos monoclonales anti-actina de músculo liso.
Se realizó análisis mediante IHC de tejido cardiaco de ratón teñido con x-gal utilizando el anticuerpo monoclonal primario anti-actina de músculo liso de ratón para identificar los miofibroblastos.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
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.

Forma física

Solution in 0.05 M Tris buffer, pH 8.0, containing 1 mM MgCl2, 1% bovine serum albumin, 50% glycerol, and 15 mM sodium azide as a preservative.

Enhanced endothelial permeability leading to intimal accumulation of low-density lipoproteins (LDL) stimulates the formation of atherosclerotic lesions. Histamine is known to increase vascular permeability. Whether this affects the formation of atherosclerotic lesions, however, remains elusive. Apolipoprotein E-null (ApoE(-/-)) mice treated
