Application of animal-free recombinant bioactive protein supplements to improve the performance of cell-based viral vaccine production

The development and regulatory approval of continuous cell lines for manufacturing viral vaccines has brought numerous benefits to production processes. We and others have contributed to upstream advances by improving cell culture media with the development of animal-free and chemically-defined recombinant protein supplements. The supplements developed include recombinant insulin-like growth factor-I (LONG®R3IGF-I), epidermal growth factor (LONG®EGF), transforming growth factor-α (LONG®TGF-α), transferrin (CellPrime™ rTransferrin AF), and albumin (CellPrime ™rAlbumin AF-G or -S). Extensive literature on the action of these bioactive proteins…
