MAMMALIAN EXPRESSION VECTORS 2<br />
PromTest - Ten Promoters to Choose From<br />
Promoters regulate differently gene expression depend<strong>in</strong>g on the cellular context. To help you determ<strong>in</strong>e easily and rapidly the best promoter<br />
for your cell l<strong>in</strong>e, InvivoGen offers PromTest , a collection of ten ubiquitous promoters driv<strong>in</strong>g the GFP reporter gene.<br />
➥ Ten ready-to-use promoters with different levels of expression<br />
➥ Drive GFP expression for convenient monitor<strong>in</strong>g of promoter strength<br />
➥ Cost-effective<br />
Description<br />
PromTest is a collection of ten ubiquitous composite promoters provided <strong>in</strong> the pDRIVE5-GFP<br />
plasmid. These composite promoters were generated by assembl<strong>in</strong>g enhancers, core promoters<br />
and 5’UTRs of different orig<strong>in</strong>s. The activity of each comb<strong>in</strong>ation depends on the cellular context<br />
(see graphs).<br />
pDRIVE5-GFP features a GFP reporter gene for convenient monitor<strong>in</strong>g of promoter activity. The<br />
strength of each promoter can be assessed qualitatively by fluorescence microscopy and<br />
quantitatively us<strong>in</strong>g a fluorometer or flow cytometry.<br />
pDRIVE5-GFP plasmids are selectable <strong>in</strong> E. coli with Zeoc<strong>in</strong> .<br />
PromTest conta<strong>in</strong>s 5 μg of each plasmid, enough for multiple transfections us<strong>in</strong>g your favorite<br />
reagent or technique. pDRIVE5-GFP plasmids can be amplified <strong>in</strong> any common E. coli laboratory<br />
stra<strong>in</strong>s. They are also available <strong>in</strong>dividually as 20 μg high-quality endotox<strong>in</strong>-free DNA.<br />
Once you have determ<strong>in</strong>ed the best promoter for your cell l<strong>in</strong>e and application, you can either<br />
replace the GFP gene with your gene of <strong>in</strong>terest, or subclone the promoter <strong>in</strong>to another plasmid<br />
with mammalian selection, such as InvivoGen’s pSELECT.<br />
Evaluation of PromTest <strong>in</strong> different cell l<strong>in</strong>es: HeLa (human cervical cancer) and CHO (ch<strong>in</strong>ese hamster ovary) cells were transiently transfected with each of the 10 pDRIVE5-<br />
GFP plasmids of PromTest us<strong>in</strong>g LyoVec (cat. code: lyec-12). The strength of the various promoters was analyzed by flow-cytometry 48h after transfection.<br />
