For cloning your gene of interest into a high expression level plasmid.
pmaxCloningTM Vector is an eukaryotic expression plasmid to promote constitutive expression of cloned DNA inserts in mammalian cells. The pmaxCloningTM Vector backbone contains immediate early promoter of cytomegalovirus (PCMV IE)* for protein expression, a chimeric intron for enhanced gene expression and the pUC origin of replication for propagation in E. coli. The bacterial Promoter (P) provides kanamycin resistance gene expression in E. coli. The multiple cloning site (MCS) is located between the CMV promoter and the SV40 polyadenylation signal (SV40 poly A). The pmaxCloningTM Vector can be used for both transient and stable expression of genes. For stable expression the pmaxCloningTM Vector must be co-transfected with an expression vector containing a selectable gene for mammalian cells.
Cloning of DNA insert
The pmaxCloningTM Vector does not contain an ATG initiation codon. A translation initiation sequence must be incorporated if the DNA fragment to be cloned does not have an initiating ATG codon or an optimal sequence for initiating translation, such as the Kozak sequence [GCC(A/G)CCATGG].
Expression in mammalian cells
pmaxCloningTM Vector can be transfected into mammalian cells by any known transfection method. The CMV promoter provides strong, constitutive expression of the cloned DNA insert in many cell types.
