Gene and Cell Therapy rely on the use of modified viruses as vectors to transfer genes into cells that they are able to infect. Modified viruses used as vectors are derived from adeno-associated viruses (AAV), lentiviruses, retroviruses and adenoviruses. These viral vectors first need to be produced in mammalian cells. Production of viral vectors is dependent on efficient transfection of one to several plasmid DNA containing the necessary viral genome to produce recombinant viral particles.
Protein production consists in overexpressing recombinant proteins (eg. antibodies) and peptides mainly in mammalian cell lines HEK-293, CHO and derivatives. Transfection of plasmid DNA encoding for the protein of interest in a given cell line can be used for both transient and stable protein production. Transient protein expression allows generation of high protein amounts in a short amount of time and can offer a reliable alternative to production of stable cell lines for proof of concept studies and tools validation. Polyplus-transfection has developed a range of products specifically designed for protein production in CHO and HEK-293 cells grown in suspension in synthetic serum-free media.
Non-viral in vivo delivery reagents are the most powerful alternative to viral vectors for nucleic acid delivery. They offer substantial advantages in terms of reliability, safety and costs for nucleic-acid based therapies. Different quality grades of in vivo transfection reagents are available for proof concept studies, preclinical studies and clinical trials.
