Wild type: only one band at 255 bp with primers F2/R2(mIl2);

Homozygous: only one band at 320 bp with primers F1/R1(hIL2); 

Abbr.. M, DNA marker; HO, homozygous; HE, heterozygous; WT, wild type.

图2 ELisa检测IL2人源化杂合子(HE)小鼠中人源IL2的表达。IL-2-HU小鼠使用刀豆蛋白刺激4h后,取血清进行Elisa检测,结果显示IL2人源化杂合子小鼠中人源IL2表达活跃,符合预期。

图3 Elisa检测IL2人源化杂合子(HE)小鼠中鼠源IL2的表达。使用刀豆蛋白刺激4h后,取血清进行Elisa检测,结果显示WT小鼠鼠源IL2表达活跃,HE小鼠鼠源IL2表达明显降低,符合预期。

图4 FACS 检测IL2人源化小鼠脾脏中人源IL2的表达。

取IL2人源化小鼠脾脏细胞使用“Leukocyte Activation Cocktail, with BD GolgiPlug”刺激4h后进行流式验证。结果显示: IL2人源化纯合子小鼠脾脏中只能检测到人源IL2的表达,无法检测到鼠源IL2的表达。
