Description: This SMMS-1 monoclonal antibody reacts with both isoforms of the human smooth muscle myosin heavy chain (SM1 and SM2) structural proteins, which are components of the contractile apparatus in smooth muscle cells. Smooth muscle myosin heavy chains are expressed by myoepithelial cells and also serve as the terminal differentiation marker for smooth muscle cells. In normal breast tissue, myoepithelial cells compose the outer layer of the lumen lining. In benign and in situ breast lesions, the intact myoepithelial layer stains with SMMS-1 and the loss of this staining indicates invasive cancer. This SMMS-1 antibody has also been reported to cross-react with bovine, canine, feline, and rat smooth muscle myosin heavy chains.
Applications Reported: This SMMS-1 antibody has been reported for use in microscopy, immunohistochemical staining of frozen and formalin-fixed paraffin embedded tissue sections, and immunocytochemistry.
Applications Tested: This SMMS-1 antibody has been tested by immunohistochemistry of formalin-fixed paraffin embedded human tissue using low pH antigen retrieval at less than or equal to 20 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.

SM-MHC is a cytoplasmic structural protein, which is a major component of the contractile apparatus in smooth muscle cells. Expression of smooth muscle myosin is developmently regulated, appearing early in smooth muscle development, and is specific for smooth muscle development. Two isoforms of smooth muscle myosin heavy chain have been identified, designated MHC-1 and MHC-2.
