The most frequent picture emerging from the studies on a variety of biological systems including normal and transformed cell lines (1, 2), intercellular matrix (3), tissular cells (4), etc., shows five molecular classes of glycosaminoglycans (GAGs); hyaluronic acid (HA), heparan sulfate (HS), dermatan sulfate (DS), chondroitin-4-sulfate (C4S), and chondroitin-6-sulfate (C6S). 2 Many difficulties have been encountered in the resolution of the components of this heterogeneous family of molecules. Presently a combination of various techniques is required in order to identify single GAGs: two-dimensional electrophoresis (5) which does not allow direct comparison, ion-exchange chromatography, and enzyme degradation or chemical breakdown with identification of the hydrolysis products (6). We describe here a very rapid, inexpensive, and highly reproducible technique which, compared with other electrophoretic procedures, exhibits the following advantages: possibility to compare directly up to eight samples in a single run; very short migration time (10-30 min); high sensitivity (0.1/xg per compound); improved resolution of all the five compounds most frequently described in biological samples; a greater manageability of the sheet and no need to
