Provided herein are, inter alia, methods for preparing a liquid cell culture media that has lesser lot-to-lot analytical variation, increased performance, and has lesser metal ion concentrations compared to a liquid media prepared by traditional methods. Such liquid media may be used for culturing cells, including but not limited to, recombinant cells.

Cell culture media, concentrated media and feeds, methods of manufacturing cell culture media and feeds, and methods of culturing cells are provided. One or more small peptides, including dipeptides are added to the cell culture media to provide improved stability and improved conditions for culturing cells.

Cell culture media, such as chemically defined cell culture media, are provided, as are methods of using the media for cell growth (i.e., cell culture) and polypeptide (e.g., antibody) production. Compositions comprising polypeptides produced by the methods are also provided.
