DESCRIPTION

• Notes: To generate a Nectin-4 stable cell line, remove the growth medium 48 hours after transduction and replace it with fresh growth medium containing the appropriate amount of puromycin (as pre-determined from a killing curve) for antibiotics selection of transduced cells. Visit bpsbioscience.com/cell-line-faq for guidelines on performing a kill curve. Biosafety: None of the HIV genes (gag, pol, rev) will be expressed in the transduced cells, as they are expressed from packaging plasmids lacking the packing signal and are not present in the lentivirus particle. Although the pseudotyped lentiviruses are replication-incompetent, they require the use of a Biosafety Level 2 facility. BPS Bioscience recommends following all local federal, state, and institutional regulations and using all appropriate safety precautions.

• Background: In contrast to other Nectins, which are found extensively in adult tissues, Nectin4 is abundant during fetal development but declines in adult life. However, its expression is elevated specifically in lung, breast, pancreas, and ovarian cancers, and is associated with poor prognosis. Nectin4 modulates the expression of proteins involved in the epithelial-mesenchymal transition via the PI3K/AKT pathway. In addition, Nectin4 ligand for TIGIT in cancer cells. It is considered a promising target for cancer immunotherapy.
• Description: The Nectin-4 Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce nearly all types of mammalian cells, including primary and non-dividing cells. The particles contain a human Nectin-4 (NM_ 030916.2) driven by an EF1A promoter and a puromycin selection marker (Figure 1).
