摘要:

以PELO 全长cDNA 为模板,采用TOPO 克隆的方法, 将人的PELO 基因克隆到pENTR-D-TOPO 载体上,形成pENTR-D-PELO 克隆载体。然后通过同源重组将含有EF1α 启动子的pENTR-5’-EF1α 和pENTR-D-PELO 重组到表达载体p2k7 上, 形成EF1α-PELO-p2k7 表达载体。将构建好的PELO 高表达载体在293FT 细胞中制备成相应的慢病毒表达载体,并用慢病毒侵染人胚胎干细胞,最终成功实现在人胚胎干细胞中稳定且高效地表达PELO 蛋白。

Abstract:

Using full length human PELO cDNA as template, TOPO cloned PELO gene to pENTR-D-TOPO vector to form the pENTR-D-PELO vector, then performed the MultiSite Gateway LR recombination reaction between pENTR-5’-EF1α and pENTR-D-PELO to get the EF1α-PELO-p2k7 expression vector. PELO overexpression lentivirus was produced in 293FT cells and ransducing human embryonic stem cells to overexpress PELO.
