- Equal numbers HK-2 cells were incubated in media containing either buffer (control) or gp120 (1, 10, and 100 ng/ml) for 16 hr. At the end of the incubation period, cells were harvested and prepared for the measurement of caspase-3 activity with the use of caspase-3 assay kit. Results (means ± SEM µM release of caspase-3) are from four sets of experiments.
- * p < 0.001 compared with control, gp120, 1 ng/ml and gp120, 100.0 ng/ml.
- ** p < 0.001 compared with control and gp120, 1.0 and 10.0 ng/ml.
