Lentiviral Vector Pseudotypes: Precious Tools to Improve …

WebThe stability of envelope-pseudotyped lentiviral vectors Lentiviral vectors have become popular tools for stable genetic modification of mammalian cells. In some applications of lentiviral vector-transduced cells, infectious-lentiviral particles should be absent. To pseudotype your viral vector, you use the same protocol for generating lentivirus, but you use a different envelope glycoprotein instead of the wild-type glycoprotein. The pseudotyped protein is encoded on the envelope plasmid which contains a promoter, the envelope gene, and a polyA tail. See more Lentiviruses and retroviruses typically target immune cells with their wild-type envelopes. However, pseudotyping allows these viruses to infect … See more A commonly used envelope protein for pseudotyping is VSV-G, or vesicular stomatitis virus G protein.
