in this study we directly compared the neutral red vital dye uptake and clonogenic survival assays and confirmed in both assays that tnf-sensitive ( l-929 ) and tnf-resistant ( emt-6 ) phenotypes show greatly reduced survival when treated with combined recombinant human tnf ( 1.0-0.0005 micrograms/ml ) and hyperthermia ( 1-2 h at 43 degrees c ) .
