  • CELL CULTURE METHOD USING AMINO ACID-ENRICHED MEDIUM
    Publication number: 20230272336
    Abstract: Methods of culturing cells capable of producing desired proteins to obtain the proteins by use of a medium from which biological components are excluded as much as possible are provided. Specifically, a culture method characterized by culturing while maintaining a specific amino acid in a culture solution at a high concentration, and a cell culture fed-batch medium for use in the method are provided.

  • Peptide-containing culture medium for culturing animal cell
    Patent number: 8252557
    Abstract: Disclosed is a culture medium for culturing an animal cell, which is characterized by containing a peptide comprising, as a constituent unit, an amino acid residue selected from the amino acid group consisting of serine, tyrosine and cysteine. The culture medium is suitable for the high level production of a protein by an animal cell.
