[Characteristics of T-Suppressors concentrated by elution from an allogeneic cell monolayer].
Quantitative enrichment of the immune lymphocyte fraction with H-2 antigen-specified suppressor cells was obtained by their elution from the relevant allogeneic monolayer of target cells. This was accompanied by 2-3-fold gain in the content of T lymphocytes and DNA synthetizing cells, as well as in the total (3)H-thymidine incorporation resulting from an increase in the percentage of medium and large lymphocytes in the population and also in the proportion of DNA synthesizing small and medium lymphocytes. Complete abolition of the suppressor effect by treatment with anti-Thy-1 and anti-T antibodies rather than with anti-B serum, and the resistance of this effect to carrageenan and carbonyl iron indicate the T cell nature of the eluted suppressor cells.
