| BL3 cells | Raji cells | |
| PBS | 36 ± 4b | 46 ± 2e |
| LKT(−) | 35 ± 3b | 46 ± 2e |

a
A total of 3 × 106 BL3 or Raji cells/ml were exposed to 40.0 μg of LKT per ml for 3 min at 25°C. Values are means ± standard deviations (n = 3). Means in each column with different superscript differ (P < 0.05). ND, not done.
