Lentivirus vector is a powerful way to transfer the target gene sequence into common cells and cells that are difficult to be transfected. By infecting cells, lentivirus transduces the target gene into the genome of the target cell, so that the target gene can be continuously expressed in vivo and in vitro. In order to obtain high titer and stable and uniform lentivirus, the packaging, purification and titer determination of lentivirus need a long time and sufficient experience. Chengzhi biology has a professional lentivirus packaging team to ensure the high quality of products.
