          Abstract

          A method for rapid fractionation of normal and leukemic T-cells (Jurkat, RPMI-8402, MOLT-4), using lectin-affinity column chromatography, is described. CNBr-activated Sepharose 6MB was used as a non-mobile phase. The gel was covalently conjugated with Dolichos biflorus agglutinin (DBA) over 24 h. The normal cells were eluted by phosphate buffered saline (Ca(2+) and Mg(2+) free), while the leukemic T-cells, interacting with DBA, were removed by N-acetyl-D-galactosamine or by low-concentrated acetic acid as a mobile phase. The cell fractions were detected spectrophotometrically at 600 nm. The rate of cell elution decreased in the order: normal>leukemic T-cells. The viability and the type of separated T-cell fractions were characterized by flow cytometry, using adequate fluorescent antibodies. The interactions between leukemic T-cells and DBA-saturated Sepharose beads were examined by fluorescent microscopy, using fluorescent isothiocyanate-DBA as a fluorescent marker.
