The present disclosure relates to methods for producing lentiviral vector-producing cells. Specifically the methods utilize two plasmids, rather than four, to provide the required packaging elements and transfer vector to a cell, allowing for the production of a large number of lentiviral producer cells, including suspension-based cells, and the production of high amounts of lentivirus. These methods allow for the production of cells that can be later induced to produce lentivirus, and can be tailored to include a specific gene of interest.

Methods and constructs for production of lentiviral vector

The present disclosure provides an automated method of producing viral vectors, utilizing engineered viral vector-producing cell lines within a fully-enclosed cell engineering system. Exemplary viral vectors that can be produced include lentivirus vectors, adeno-associated virus vectors, baculovirus vectors and retrovirus vectors.

Automated production of viral vectors

The present disclosure relates to a mammalian cell line for producing adeno-associated virus (AAV), suitably including nucleic acids encoding helper genes and AAV genes, under the control of derepressible promoters. The disclosure also relates to isolated nucleic acid molecules that encode such genes, as well as methods of using the mammalian cells for producing AAVs.
