The FOLR1 (Folate receptor alpha) Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles ready to transduce nearly all types of mammalian cells, including primary and non-dividing cells. These viruses transduce cells with the Macaca fascicularis (also known as crab-eating macaque or cynomolgus monkey) FOLR1 gene.
