Fractionation of human T lymphocytes on wheat germ agglutinin-sepharose
U Hellstrom, ML Dillner, S Hammarstrom and P Perlmann
T cells from human peripheral blood was purified by fractionation on
columns charged with human immunoglobulin and rabbit anti-human immuno-
globulin. When assayed with 125I- or fluorescein isothiocyanate-labeled
wheat-germ agglutinin (WGA), a weakly binding and a strongly binding
subpopulation could be distinguished. These T-cell subpopulations were
fractionated on columns charged with WGA, convalently bound to Sepharose
6MB. The cells responding to the mitogens leukoagglutinin from Phaseolus
vulgaris and concanavalin A were enriched in the strongly binding
subpopulation (approximately 20% of the T cells) while they were depleted
from the weakly binding subpopulation.
