| 方法 | For both assays, cells were starved overnight and treated the following day with increasing concentrations of CP-673,451 for 30 minutes at 37°C. During the final 5 to 8 minutes of incubation, either stem cell factor (50 ng/mL) or PDGF-BB (500 ng/mL) was added. Unstimulated cells were used as phosphorylation controls. Cells were washed, lysed, and equivalent protein levels were separated by PAGE. Following transfer to nitrocellulose, membranes were blotted to detect phospho-PDGFR (pY857 antibody, Santa Cruz) or phospho-c-kit (pY719 antibody, Cell Signaling) antibody at 1: 200 overnight at 4°C. Densitometry of bands and IC50 calculation were measured using a LumiImager (Roche, Indianapolis, IN). |

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。
