pDRIVE is a family of plasmids with an expanding collection of native and composite promoters.
Promoters are valuable tools to study the expression of a given gene both in vitro and in vivo. Now with pDRIVE, you can choose to express your gene of interest at high or low levels, ubiquitously or specifically, and in a constitutive or inducible manner.

pDRIVE plasmids contain the LacZ reporter gene which expression can be determined using chromogenic, luminescent or histochemical detection. These plasmids are selectable with Zeocin™ in E. coli.


Native or Composite Promoters
Native promoters, also called minimal promoters, consist of a single fragment from the 5’ region of a given gene. Each of them comprises a core promoter and its natural 5’UTR. In some cases, the 5’UTR contains an intron.
Composite promoters combine promoter elements of different origins (e.g. SV40 enhancer/AFP promoter) or were generated by assembling a distal enhancer with a minimal promoter of the same origin (e.g. CEA enhancer/promoter).

Various Expression Patterns
Ubiquitous Promoters, strongly active in a wide range of cells, tissues and cell cycles.
Tissue-Specific Promoters, active in a specific type of cells or tissues.
Tumor-Specific Promoters, active specifically in tumor cells.

Plasmid Features

pDRIVE map


• LacZ gene encodes β-galactosidase an enzyme that catalyzes the hydrolysis of X-Gal, producing a blue precipitate that can be easily visualized under a microscope.

• SV40 pAn: The Simian Virus 40 late polyadenylation signal enables efficient cleavage and polyadenylation reactions resulting in high levels of steady-state mRNA.

• pMB1 Ori is a minimal E. coli origin of replication with the same activity as the longer Ori.

• EM7 is a bacterial promoter that enables the constitutive expression of the antibiotic resistance gene in E. coli.

Sh ble gene confers zeocin resistance, therefore, allowing the selection of transformed E. coli carrying a pDRIVE plasmid. Note: Stable transfection of clones cannot be performed due to the absence of a eukaryotic promoter upstream of the Sh ble gene.

Easy Subcloning of the Promoters
In every pDRIVE, several unique restriction sites flank the promoter (a multiple cloning site at the 5’ end and Nco I or Bsp HI at the 3’ end) in order to excise the promoter easily. These restriction sites are compatible with many other enzymes, thus facilitating cloning. Other restriction sites may be introduced by performing PCR using primers containing the restriction sites of interest.
