in this study, in order to facilitate and accelerate the production of eukaryotic protein alpha 1-antitrypsin (aat) with correct post-translational modifications, a protein production system based on the transduction of cho and cos-7 cells using lentiviral vectors was developed. human aat cdna was cloned into a replication-defective lentiviral vector. the transgene aat-jred chimer was transferr...
