Generate your desired constitutively or inducible expression stable cell lines at best price!
GenTarget's stable cell line service can build your cell line at a very cost effective way. Using our proprietary lentiviral vectors, We subclone your target gene into our lentivector, generate the lentivirus particles, sequentially infect the cell line you desired, and select the clones constantly expressing your gene at high level. For inducible expression cell line, we infect the cell with the repressor particles (TetR) first to make the TetR stable cell line, then infect the target expression particle to finally generate the Tetracycline inducible stable cell line.
Our proprietary Tet inducible suCMV promoter has the strongest expression efficiency, will provide extremely high level of expression for your target. We will work with you to ensure that the cell line meets your requirements. Our unique technology ensures a fast turn around time as less as 2 month for each cell line creation. Cell lines are shipped as cryopreserved vials after validating the target gene's integration. You will get the best quality and best price.

What's the advantages for using lentivirus to generate stable cells?
To make stable cell line, taeget has to be intergraded into host cells' genome for a stable, constitutive expression. Randomly integration (that such as by transfection) demonstrates large variety expression dependent upon the transcription levels at integration sites. And random integration often resulted in the independent integration between the target and the selection marker, which lead to large scale of screening works for selecting the positive clone (resistant with high expression). In general, less than 10% resistant clones express the transgene. In contrast, lentivrius transduction has a tendency to integrate in high transcription level sites (hot-spots) with a full virus genome. Besides, engineered lentiviral transfer vector that embedded a matrix-attachment region (MARs) sequence may provide position-independent transgene expressions. Compared to conventionally stable cell line construction, lentivirus has much higher positive clone rate and target is always co-exist with the selection marker, thus substantially reduces the cost, labor and time in selection of high-level expression stable clones.
Why use GenTarget's stable cell line service:
Engineered in house lentiviral vector for high efficient gene integration into cell genome with extremely low false positive clones;
Self-inactivating (safe to use) and high-titer lentiviral particles can delivery your gene into a wide range of cell lines including non-dividing, primary or stem cells;
Target protein expression can be traced and monitored by a fluorescent image, suitable for sorting or selecting the integrated cells (noticed: the fluorescent protein is not fuioned with your target);
