RECOMBINANT PROTEIN PRODUCTION IN A HUMAN CELL USING SEQUENCES ENCODING ADENOVIRUS E1 PROTEIN

摘要

The present invention provides methods and compositions for the production o f recombinant proteins in a human cell line, using sequences encoding at least one E1 protein of an adenovirus where the cells does not encode a structural adenoviral protein from its genome. The methods and compositions are particularly useful for generating stable expression of human recombinant proteins of interest that are modified post-translationally, e.g. by glycosylation. Such proteins may have advantageous properties in comparison with their counterparts produced in non-human systems like Chinese Hamster Ovary (CHO) cells.
