WebNov 29, 2013 · Most bioassays measured the proliferative effect of IL-2 on the murine cytotoxic T cell-line, CTLL-2 or the HT-2 cell-line but employed different readouts for assessing the proliferation (Gillis et al., 1978, Gieni et al., 1995). In one laboratory, however, the human T cell-line, KIT 225 was used (Hori et al., 1987).
