A rapid in vitro cytotoxicity assay for the detection of tumor necrosis factor on human BT-20 cells.


This report describes a rapid, reproducible in vitro bioassay to quantitate the cytotoxic activity of human tumor necrosis factor-alpha using a human rather than murine cell line in the absence of metabolic inhibitors. The target cells are BT-20 (breast carcinoma) cultured at 39 degrees C in the presence of recombinant human tumor necrosis factor-alpha… (More)
