生物活性
MNI caged kainic acid is a Kainic acid (Cat.No. 0222) caged with the photosensitive 4-methoxy-7-nitroindolinyl group. Generates large inward currents at resting membrane potential upon wide field photolysis in Purkinje neurons. Selectively photoactivates kainate receptors when used in conjunction with an AMPA antagonist, such as GYKI 53655 (Cat.No. 2555). Suitable for uncaging with 300-380 nm excitation. Exhibits rapid uncaging rate relative to ionotropic glutamate receptor activation. Also suitable for two-photon uncaging experiments at 720 nm.
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
重量 (kg)体表面积 (m2)Km系数
0.020.0073
动物 B的Km系数动物 A的Km系数
大鼠0.150.0256
兔1.80.1512
豚鼠0.40.058
仓鼠0.080.025
狗100.520
动物 A (mg/kg) = 动物 B (mg/kg) ×
例如，依据体表面积折算法，将白藜芦醇用于小鼠的剂量22.4 mg/kg 换算成大鼠的剂量，需要将22.4 mg/kg 乘以小鼠的Km系数（3），再除以大鼠的Km系数（6），得到白藜芦醇用于大鼠的等效剂量为11.2 mg/kg。
