| Abstract: | We generated a monoclonal antibody (MAb), designated LN-6, directed against human vimentin, which retains its immunoreactivity in B5-fixed, paraffin-embedded tissues. Like other anti-vimentin MAb, LN-6 was found to be reactive with a wide spectrum of human sarcomas and normal cells of mesenchymal derivation. However, unlike other similar reagents, LN-6 was unreactive with normal and malignant human lymphoid cells and therefore displays a more restricted immunoreactivity. Because of its ability to stain routinely processed pathological tissues and its marked reactivity with human sarcomas, LN-6 is a unique reagent for the immunohistochemical diagnosis of human cancer. |
