General description

Monoclonal Anti-Actin, α-Smooth Muscle (mouse IgG2a isotype) is derived from the 1A4 hybridoma produced by the fusion of mouse myeloma cells and splenocytes of immunized BALB/c mice.
The antibody (also known as anti-α-Sm-1) is specific for the single isoform of α-smooth muscle actin. It reacts specifically with α-smooth muscle actin in immunoblotting assays and labels smooth muscle cells in frozen or formalin-fixed, paraffin-embedded tissue sections.

Immunogen

N-terminal synthetic decapeptide of α-smooth muscle actin.

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Flow cytometry/Cell sorting (2 papers)
Immunocytochemistry (3 papers)
Immunofluorescence (13 papers)
Immunohistochemistry (27 papers)
Western Blotting (2 papers)
Immunocytochemistry was performed on smooth muscle cells from bovine aortas using the monoclonal anti-ACTA2 antibody. Cells were first grown on glass cover slips and fixed in 50% acetone/EtOH for 10 minutes at 4 degrees.
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

Smooth muscle actin is transiently coexpressed with sarcomeric α-actin during myogenesis in chicken and rat embryos. It has been found in the ventricular conducting tract of adult mammalian heart. It is expressed in leiomyomas, leiomyosarcomas and leiomyoblastomas, as well as in a proportion of rhabdomyosarcomas.

Physical form

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