All of the pCMV vectors are 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 enhanced cytomegalovirus immediate-early (CMV) promoter for high-level expression in a wide range of mammalian cells.
Hygromycin resistance gene for selection of mammalian cell lines.
A Kozak consensus sequence to enhance mammalian expression.
Designed for mammalian expression, stable or transient.
Here is the sequence and map of each vector with different tags.
