GENETICALLY MODIFIED RECOMBINANT CELL LINES
20220348941 · 2022-11-03 ·

Glycoproteins that are transgenically produced in mammalian cells exhibit non-human glycan structures. As in humans, this can possibly lead to immune responses, the drug manufacturing potential of these drugs is limited. On the other hand, recombinant protein production in human cells is inefficient due to the cells' poor protein yields, proliferation potential and cellular density. The present application solves these issues by providing a recombinant vertebrate cell that is comprising a non-vertebrate and/or artificial phosphatidylethanolamine-binding protein (PEBP). Compared to a parent cell line, the recombinant cells of the invention exhibit improved cell growth, protein yield and excellent compatibility with other established protein production methods. Furthermore, methods, for producing a cell line with improved vitality, protein expression and cell growth characteristics by introducing a non-vertebrate and/or artificial PEBP is given. Moreover, both a nucleic acid construct that is suitable for regulating recombinant protein expression in a cell by coding for such a PEBP and a recombinant cell comprising such a nucleic acid construct is provided. Lastly, a method for the recombinant expression of a target protein by culturing such a recombinant vertebrate cell of the invention is given, wherein the cell is also comprising an expression construct encoding the target protein.

CONCENTRATED PERFUSION MEDIUM

The invention relates to a serum-free cell culture perfusion medium comprising the medium components subgrouped into at least three separate aqueous concentrated feeds and a diluent, wherein the resulting serum-free cell culture perfusion medium is pH-adjusting to neutral pH upon mixing. Also provided is a method of preparing said serum-free cell culture perfusion medium. The invention further relates to methods of culturing mammalian cells or producing a protein of interest in perfusion culture using said serum-free cell culture perfusion medium that achieve high productivity at a low cell specific perfusion rate. The invention further relates to the use of the new and improved serum-free cell culture perfusion medium to control osmolality in a perfusion cell culture, wherein increasing osmolality results in an increase in total productivity and/or cell specific productivity by suppressing cell growth during cell culture, e.g., during production phase of perfusion cell culture. Suppression of cell growth particularly reduces or eliminates the need for wasteful cell bleed.
