<h2 data-section-id="xs82dy" data-start="121" data-end="167">What are additional immortalization agents?</h2>
&nbsp;
Additional immortalization agents cover recombinant lentiviral constructs delivering genes other than TERT or SV40 large T antigen used to bypass replicative senescence in primary cells, most notably HPV-16 E6/E7 (which inactivate p53 and Rb similarly to SV40T but are derived from human papillomavirus), Bmi1 (a polycomb group protein that represses the p16/CDKN2A senescence pathway), cMyc, CDK4, and HOXA/HOXB family genes. Related entities include p16/CDKN2A pathway repression (Bmi1), keratinocyte and epithelial cell immortalization (HPV E6/E7), polycomb group signaling, and combination immortalization strategies.

&nbsp;
HPV E6/E7 for epithelial and keratinocyte immortalization
HPV-16 E6 and E7 proteins inactivate p53 and Rb respectively, similar in net effect to SV40 large T antigen but derived from a different viral source; E6/E7-based immortalization is particularly well-documented for keratinocytes and other epithelial cell types, and is sometimes preferred over SV40T for these lineages based on published precedent.
Bmi1 for stem and progenitor cell types
Bmi1 represses the p16/CDKN2A senescence pathway through its role in the polycomb repressive complex, and has been used to extend the proliferative capacity of hematopoietic and neural stem/progenitor cells in research settings; confirm the specific cell type has documented precedent for Bmi1-based extension before relying on it as a primary immortalization strategy.
cMyc and CDK4 as proliferation-driving factors
cMyc and CDK4 overexpression can drive proliferation and contribute to immortalization, often used in combination rather than as standalone immortalization agents; review the specific combination strategy in the source literature before ordering individual components.
E6/E7 separate vs. fused constructs
HPV E6/E7 may be delivered as separate genes or as a fused open reading frame; confirm which configuration a published protocol specifies, since this can affect relative expression levels of the two proteins.

&nbsp;
Additional immortalization agent lentiviruses are typically supplied at titers around 1x10^8 TU/mL, shipped on dry ice and stored at -80&deg;C, with antibiotic or fluorescent-antibiotic fusion selection markers consistent with other immortalization lentivirus products. Pack sizes for academic labs commonly consist of small-volume aliquots sufficient for multiple transduction attempts, with constructs validated by sequencing and tested free of common contaminants.&nbsp;
This sub-category sits within MBP's cell immortalization catalog alongside TERT overexpression viruses and SV40T antigen overexpression viruses. Labs constructing custom combination vectors can also review MBP's cloning reagents. MBP's specialist team can help confirm which immortalization agent has documented precedent for a specific cell type before order placement.
