This antibody is specific to alpha-smooth isoform of actin. It reacts with smooth muscle cells of vessels and different parenchymes. The antibody does not cross-react with beta and gamma-cytoplasmic, alpha-sarcomeric and alpha-myocardial actin isoforms. Cellular Localization: Cytoplasmic.
Purification

Immunohistochemistry on Formalin Fixed Paraffin Embedded Sections: Use Actin antibodyat 1/25-1/50 dilution in an ABC method for 30 minutes at room temperature. Recommended Positive Control: Leiomyoma. Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
Smooth muscle actin is expressed in normal smooth muscle and in myoepithelial cells, and also in tumours derived from these cells. Actins are involved in maintaining the structure and integrity of a cell, as well as cell motility. They are highly conserved proteins and make up the majority of the contractile apparatus. To date, six different actin isoforms have been described.Synonyms: ACTSA, ACTVS, Alpha-actin-2, Cell growth-inhibiting gene 46 protein
