Lentiviral vectors are tool vectors based on HIV-1 and developed using the herpesvirus VSVG envelope protein. They have a broad host range and can efficiently infect both dividing and non-dividing cells. Once inside the host cell, the lentivirus uses reverse transcriptase to convert its RNA into double-stranded DNA, which then integrates permanently into the host genome, enabling long-term stable expression. Based on the customer’s gene information and specific requirements, Energy designs customized solutions to construct overexpression lentiviral vectors. The packaged viral particles can be used for both in vitro and in vivo experiments.
