Abstract
Vimentin enriched in cytoskeletal frameworks by Triton X-100 extraction of Ehrlich ascites tumor cells and purified from a low ionic strength extract of the cell residues by (NH4)2SO4 precipitation and DEAE-Sepharose and ssDNA-cellulose chromatography in the presence of 6 M urea was highly contaminated with lipids. Thin-layer chromatography of a chloroform-methanol extract of the purified protein revealed, besides small amounts of phospholipids, the presence of large quantities of neutral lipids.Keywords
