方法 | GTPγS Binding Assay 15 μg of membranes were incubated for 60 min at 30 °C in a total volume of 500 μM GTPγS binding assay buffer (50 mM Tris-HCl, pH 7.4, 3 mM MgCl2, 0.2 mM EGTA, and 100 mM NaCl) with unlabeled ligand (at least nine different concentrations were used ranging between 100 pM and 100 μM), 0.1 nM [35S]GTPγS (1250 Ci/mmol; PerkinElmer Life Sciences), 10 μM GDP, and 0.1% (w/v) BSA. The basal GTPγS binding was measured in the absence of ligand. Nonspecific binding was determined with 10 μM unlabeled GTPγS (Sigma). The reaction was terminated by rapid filtration through Whatman GF/C filters. The radioactivity trapped in the filters was determined by liquid scintillation counting. |

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。
