Abstract
A simple method is described which allows antigen-specific suppressor T cells to be enriched by greater than 100-fold. The enriched cells have the following characteristic markers: Ig-, Thy-1+, Ly-1-, Ly-2,3+, and I-J+. More than 30% of this population could be killed directly by an antiserum specific for the I-J subregion gene product in the presence of complement.
