Lentivirus vector is a gene therapy vector developed on the base of HIV-1 (human immunodeficiency virus type 1). Lentivirus vector is a powerful tool for introduction of exogenous genes, with the advantages of wide infection spectrum, effective infection and long-term stable expression of exogenous genes. Now the lentivirus system has been widely used in various cell lines for gene overexpression, RNA interference, microRNA research, as well as in vivo experiments.
