General description

Mouse monoclonal antibody. Recognizes α-actin in smooth muscle cells.
Recognizes α-actin in smooth muscle cells of blood vessels and parenchymal tissue of the intestine, testis, and ovary. Does not recognize actin from fibroblasts (β- and γ-cytoplasmic), striated muscle (α-sarcomeric), or myocardium (α-myocardial).

    • This Anti-α-Actin Mouse mAb (1A4) is validated for use in Frozen Sections, Immunoblotting, Paraffin Sections for the detection of α-Actin.

    Immunogen

    Human Smooth Muscle
    a synthetic peptide corresponding to amino acids 1-10 of human smooth muscle α-actin.

    Application

    Frozen Sections (1:50-1:75)

    Immunoblotting (see comments)

    Paraffin Sections (1:50-1:75)

    Packaging

    Please refer to vial label for lot-specific concentration.

    Warning

    Toxicity: Standard Handling (A)

    Physical form

    In 150 mM NaCl, 20 mM Tris-borate, BHC-6 carrier polysaccharides, pH 7.5.

    Analysis Note

    Negative Control
    Fibroblasts, striated muscle, or myocardium
    Positive Control
    Smooth muscle cells of blood vessels and parenchymal tissue of intestine, testis, or ovary

    Other Notes

    Does not recognize actin from fibroblasts (β- and γ-cytoplasmic), striated muscle (α-sarcomeric), or myocardium (α-myocardial).Prolonged fixation in buffered formalin destroys the epitope. The antibody is specific for the α-smooth muscle isoform of actin. This antibody is also reported to work for immunoblotting. Variables associated with assay conditions will dictate the proper working dilution.
