■ 質(zhì)粒簡介
pCDNA3.0載體是專門設(shè)計(jì)用來在哺乳細(xì)胞中進(jìn)行高水平的穩(wěn)定表達(dá)和瞬時(shí)表達(dá)。其中人巨細(xì)胞病毒早期啟動(dòng)子（CMV）在廣泛的哺乳動(dòng)物細(xì)胞中可以實(shí)現(xiàn)高表達(dá)。另外為篩選穩(wěn)定細(xì)胞系提供了新霉素抗性基因，可用G418篩選。
pcDNA3.0 is 5.4 kb vectors designed for high-level stable and transient expression in mammalian hosts. High-level stable and non-replicative transient expression can be carried out in most mammalian cells. The vectors contain the following elements: Human cytomegalovirus immediate-early (CMV) promoter for high-level expression in a wide range of mammalian cells. Neomycin resistance gene for selection of stable cell lines.
pcDNA3.0 vector is designed for high-level, constitutive expression in a variety of mammalian cell lines. It contains a Geneticin selectable marker and a forward-orientation multiple cloning site. High-level stable and non-replicative transient expression can be carried out in most mammalian cells. The vectors contain the following elements: Human cytomegalovirus immediate-early (CMV) promoter for high-level expression in a wide range of mammalian cells Multiple cloning sites orientations to facilitate cloning .Neomycin resistance gene for selection of stable cell lines Episomal replication in cells lines that are latently infected with SV40 or that express the SV40 large T antigen.
