Chemically-Defined Protein-Free Feed Media: BalanCD® CHO Feed 1

BalanCD® CHO Feed 1 is a chemically-defined protein-free feed medium designed to provide cell culture nutrients for fed-batch applications in conjunction with BalanCD CHO Growth A. The feed supplement has been developed to promote cell growth and MAb production in a variety of Chinese Hamster Ovary (CHO) cells. This formulation was developed using Irvine Scientific's Rational Culture Media Design™ approach to carefully balance key nutrients that provide superior yields in CHO fed-batch applications.

BalanCD CHO Feed 1 is comprised solely of animal component-free, chemically defined components, contains no antibiotics or antimycotics, and has proven stability in both powder and liquid formats.

Product Handling & Storage
Product handle using aseptic techniques is required to avoid contamination. Do not use if cloudy or if solution has precipitated.

Intended Use
These products are for RESEARCH USE only and not approved for human or veterinary use, for application to humans or animals, or for use in clinical or in vitro procedures.

Performance Study Design
The study consisted of three model cell lines (CHO-S, CHO-M, and CHO-dhfr) grown in fed-batch mode using Irvine Scientific’s BalanCD CHO Growth A and Feed 1 evaluated in a side by side comparative with several commercially available growth and feed media.
