图1. PD-L2人源化小鼠构建策略。

图2. RT-PCR鉴定结果图。引物对 P1/2 特异针对野生型小鼠,引物对 P3/4 特异针对PD-L2人源化小鼠。WT小鼠用 P1/2 引物对可扩增出 404bp 产物;人源化小鼠用 P3/4 引物对可扩增出 405 bp 产物。
引物对 P1/2 Wild type = 404 bp
引物对 P3/4 mutant = 405 bp
M:100bp Plus DNA ladder from Transgen (BM311)

图3 FACS 检测PD-L2人源化小鼠脾脏中人源PD-L2的表达。
PD-L2人源化小鼠通过尾静脉注射刀豆蛋白(12mg/kg)刺激4h,取脾脏细胞进行流式验证。结果显示: PD-L2人源化杂合子小鼠脾脏中既可以检测到人源PD-L2的表达,也可以检测到鼠源PD-L2 的表达;而PD-L2人源化纯合子小鼠脾脏中只检测到人源PD-L2的表达。
