Abstract

Human interleukin 2 (IL-2) derived from induced human malignant cells has been purified to homogeneity using multiple high performance liquid chromatography (HPLC) steps. The purified IL-2 exhibits potent activity promoting the long-term in vitro culture of antigen-specific effector T-lymphocytes and in modulating lymphocyte reactivity.
