| 10. | The expression efficiency difference between ped5 and pcdhfrl , a vector utilizing cmv enhancer / promoter ( pcmv - ie ) for foreign protein production , was analyzed using human interferon - p ( ifn - ) gene and human secreted alkaline phosphatase ( seap ) gene as reporters . when analyzed in transient expression , ped5 showed a little more protein produciton than pcdhfrl . however , in continuous expression , when serum concentration was lessened to slow down cell proliferation , ped5 expressed 3 . 1 times more reporter proteins than pcdhfrl , which implied that pef - io was less affected by cell cycle status in contrast to pcmv - ie , making ped5 a good expression vector for foreign protein production
应用人-干扰素( ifn - )和人分泌型碱性磷酸酶( seap )基因作为报告基因，对含有巨细胞病毒即早期启动子( p _ ( cmv - ie ) )的表达载体pcdhfr1和ped5表达外源蛋白的能力进行了比较，发现对于瞬时表达， ped5略好于pcdhfr1 ；在稳定表达中，通过降低血清浓度，使细胞增殖缓慢，这时ped5表达外源蛋白的能力较pcdhfr1高3 . 1倍。 |
