The TNFR2 (Tumor Necrosis Factor Receptor 2, or TNR1B) Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles ready to transduce almost all types of mammalian cells, including primary and non-dividing cells. These viruses transduce cells with Human TNFR2 (NM_001066.3) driven by a CMV promoter. The lentiviruses also transduce a puromycin selection gene.
