Abstract
Human T-T hybridomas are made by fusing an azaserine-hypoxanthine (AH) sensitive T leukemia cell line, preferably the AH-sensitive mutant of the Jurkat leukemia line identified as J3R7, with normal T cells and culturing the fusion product in a selective AH medium. Stable, interleukin-2 (IL-2)-producing human T-T hybridomas were made by this process.
