Actin is a major component of the cytoskeleton and is present in most cell types. This MAb is highly specific to actin from smooth muscles. Its epitope lies in the first four N-terminal amino acids. This MAb does not stain cardiac or skeletal muscle; however, it does stain myofibroblasts and myoepithelial cells. This antibody could be used together with anti-muscle specific actin and myogenin in making a diagnosis of smooth muscle and skeletal muscle tumors. In most cases of rhabdomyosarcoma, this antibody yields negative results whereas anti-muscle specific actin and myogenin are positive. Leiomyosarcomas are positive only with anti-muscle specific actin and anti-smooth muscle actin and are negative with anti-myogenin.

Applications
Suitable for use in Immunofluorescence, Flow Cytometry, FLISA, Western Blot, Immunoprecipitation, Immunohistochemistry. Other applications not tested.
Recommended Dilution
Flow Cytometry: 0.5-1ug/million cells Immunofluorescence: 0.5-1ug/ml Western Blotting: 0.5-1ug/ml Immunoprecipitation: 0.5-1ug/500ug protein lysate Immunohistochemistry (Frozen & Formalin-fixed): 0.5-1ug/ml for 30 minutes at RT No special pretreatment is required for the immunohistochemical staining of formalin-fixed, paraffin-embedded tissues. Optimal dilution for a specific application should be determined.
Positive Control
