Lentiviral vector delivery of fluorescently labeled protein expression to human neural progenitor cells. Neurospheres were allowed to differentiate on laminin-coated plates and then coinfected with equivalent amounts of Lenti-X viruses produced from a pLVX-AcGFP1-Actin vector and a pLVX-DsRed-Monomer-Nuc vector. AcGFP1-labeled actin allows clear visualization of the cytoskeleton (green), while DsRed-Monomer-labeled nuclei (red) are also visible The lentiviral genome (i.e., the genetic material enclosed in the viral particle) is delivered to a target cell upon infection. When lentivirus is used for research, it is the lentiviral genome that encodes genetic material that the researcher wants delivered to specific target cells. This genome is encoded by plasmids called transfer plasmids, which can be modified to encode a wide range of gene products. The main restrictions on a lentiviral transfer plasmid are size (i.e., a limited.
