57 kDa

Highly specific for the intermediate filament protein vimentin which is present in all cells of mesenchymal origin. This antibody is positive with cells of mesenchymal derivation, including endothelial cells and certain smooth muscle cells of the vascular tract, fibroblasts, connective tissue, all types of blood cells, including thymocytes, interstitial and testicular Sertoli cells, ovarian follicle cells. It can also be used to detect coexpression of vimentin in combination with other intermediate filament proteins. VIM 3B4 has turned out to be the most avid monoclonal antibody to vimentin. Tumors specifically detected: sarcoma (including myosarcoma), lymphoma, melanoma. The binding region of monoclonal antibody VIM3B4 has been characterized by Bohn et al. (1992). According to these authors, the epitope has been localized on the alpha-helical part of vimentin (rod domain coil 2). Due to an aa substitution at position of aa 353 in murine vimentin (that could explain for the weak cross-reaction of the antibody with murine vimentin) they were able to narrow down the binding region around position 353. These findings were confirmed by truncation mutagenesis experiments using human vimentin (Rogers et al., 1995). Polypeptide reacting: MW 57 kDa intermediate filament protein (vimentin) of mesenchymal cells.
