例句與用法
- 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
