Anti-PrPSc activity and cytotoxicity of DB772 in sheep microglial cells and Rov cells.

a50% tissue culture effective concentration (TCEC50). Values are the range in one independent experiment; two additional independent experiments confirmed the value was less than .4 μM. bValues are the mean ± one standard deviation of three independent experiments. c50% cytotoxic concentration (CC50). Values are the mean ± one standard deviation of four independent experiments. dNot determined. eNot applicable as no anti-PrPSc activity was measured.a 50%组织培养有效浓度（50% Tissue Culture Effective Concentration, TCEC50）：数值为单次独立实验的取值范围；另有两次独立实验证实该数值小于0.4 μM。b 数值为三次独立实验的平均值±标准差。c 50%细胞毒性浓度（CC50）；数值为四次独立实验的平均值±标准差。d 未测定。e 不适用，因未检测抗PrPSc活性。
