| 细胞系 | A2058, A375, M238 and M249 cell lines |
| 方法 | Colony formation assay Depending on the cell line (and plating efficiency), 200–1000 cells were seeded
into each well of a 6-well plate and treated as described in detail previously. In the case of primary melanoma cells, 1000 cells were seeded and let grow for 24 days in the presence or absence of drug treatment; because only small colonies formed, the stained colonies were counted under the microscope.Survival of melanoma cells after drug treatment. Five different melanoma cell lines (as indicated), as well as a culture of primary melanoma tissue cells (labeled ‘primary’) were exposed to increasing concentrations of TMZ (diamonds) or NEO212 (circles) for 48 hours, and long-term survival was determined via colony formation assay (CFA). |

不同实验动物依据体表面积的等效剂量转换表（数据来源于FDA指南）
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
| 重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| 体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
| 动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
| 动物 A的Km系数 |
例如，依据体表面积折算法，将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量，需要将20 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到化合物用于大鼠的等效剂量为10 mg/kg。
