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
應用人-干擾素（ ifn - ）和人分泌型堿性磷酸酶（ seap ）基因作為報告基因，對含有巨細胞病毒即早期啟動子（ p _ （ cmv - ie ） ）的表達載體pcdhfr1和ped5表達外源蛋白的能力進行了比較，發現對于瞬時表達， ped5略好於pcdhfr1 ；在穩定表達中，通過降低血清濃度，使細胞增殖緩慢，這時ped5表達外源蛋白的能力較pcdhfr1高3 . 1倍。This proliferation process stop or slow down in winter, and resumes in next march and april, mature sperm appears in august then is stored in testis, and spermiation occurs in the third march and april
