<h2 data-section-id="1vscfio" data-start="222" data-end="262">What are TERT overexpression viruses?</h2>
&nbsp;
TERT overexpression viruses are recombinant lentiviral (or in some cases retroviral) particles carrying the human telomerase reverse transcriptase (hTERT) gene under a constitutive promoter, designed to extend telomere length and bypass replicative senescence in primary cells. Related entities include telomere maintenance, replicative senescence, population doubling limits, EF1-alpha and CMV promoters, and antibiotic/fluorescent selection markers (puromycin, hygromycin, GFP-Puro).

&nbsp;
Promoter selection
EF1-alpha promoter constructs are often preferred for primary cells where CMV promoter silencing over extended culture is a concern, though CMV-driven constructs offer strong initial expression; the choice may depend on the expected culture duration and cell type-specific promoter activity.
Selection marker type
Antibiotic resistance markers (puromycin, hygromycin, neomycin/G418, blasticidin) allow selection of stably transduced populations by drug treatment, while fluorescent-antibiotic fusion markers (e.g., GFP-Puro) additionally allow visual confirmation of expression and flow sorting; confirm the target cell line's existing markers don't conflict.
Titer and transduction efficiency
hTERT lentivirus is typically supplied at titers around 1x10^8 TU/mL; transduction efficiency depends on the target cell type's susceptibility to lentiviral infection, and some difficult-to-transduce primary cells may require optimization of multiplicity of infection (MOI) or use of transduction enhancers.
Species considerations
hTERT is human-specific; for non-human primary cells, confirm whether a species-matched TERT ortholog is available or whether SV40 large T antigen (with broader documented cross-species activity) is a more appropriate alternative for the target species.

<h2 data-section-id="1fljvas" data-start="3151" data-end="3176">Specifications context</h2>
&nbsp;
TERT overexpression lentivirus is typically supplied at approximately 1x10^8 TU/mL in small-volume vials (e.g., 25 microliters per vial), shipped on dry ice and stored at -80&deg;C, with constructs validated by full-length sequencing and confirmed free of mycoplasma and common contaminants. Stable transduction and selection typically take 1-2 weeks before characterization, with full confirmation of telomere extension and extended proliferative capacity assessed over subsequent passages. As of 2026, hTERT lentivirus remains a standard tool for generating immortalized cell lines that retain much of the original primary cell's phenotype, distinguishing it from the more transformation-prone SV40 large T antigen approach.
This sub-category sits within MBP's cell immortalization catalog alongside SV40T antigen overexpression viruses and additional immortalization agents. Labs building custom expression constructs can also review MBP's cloning reagents for vector and competent cell options. MBP's specialist team can help confirm promoter and selection marker choices for a specific primary cell type before order placement.
