Basic Vector Information
The pcDNA3.4 circular vector is a constitutive mammalian expression vector designed to deliver exceptionally high levels of transgene expression. It can be used in suspension-adapted cells, such as Expi293F™, FreeStyle 293-F, and FreeStyle CHO-S cells, for transient protein expression. The vector can also be used as a Geneticin®-selectable expression plasmid for engineering stable cell lines. The enhanced, full-length CMV promoter and other expression elements typically enable higher expression levels than pcDNA 3.1-, 3.2-, and 3.3-based expression constructs.
