Chemically-Defined Protein-Free Feed Medium: BalanCD™ CHO Feed 2Source: Irvine Scientific
BalanCD™ CHO Feed 2 is a chemically-defined protein-free feed medium designed to be added as a fed-batch supplement to promote cell growth and increase process yields of antibodies and recombinant proteins.
BalanCD™ CHO Feed 2 is a chemically-defined protein-free feed medium designed to be added as a fed-batch supplement to promote cell growth and increase process yields of antibodies and recombinant proteins. BalanCD™ CHO Feed 2 improves productivity by providing essential cell culture nutrients such as glucose, amino acids and vitamins.This formulation was developed using Irvine Scientific’s Rational Culture Media Design™ strategy to overcome metabolic overflow which is frequently observed when supplementing richer growth media in fed-btach systems.The BalanCD™ CHO Feed 2 has been tested with three model cell lines (CHO-S, CHO-M, and CHO-DHFR).
BalanCD™ CHO Feed 2 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 handling using aseptic techniques is required to avoid contamination. Do not use if cloudy or if solution has precipitated. Powder product should be stored at 2-8°C and in absence of light for up to 6 months. Liquid product should be stored at 2-8°C and in absence of light for up to 1 year. Extended stability studies for both powder and liquid are ongoing for this formulation.

The study consisted of three model cell lines (CHO-S, CHO-M, and CHO-DHFR) grown in fed-batch mode using a commercially available competitor growth media paired with a feed media (BalanCD™ CHO Feed 2 or one of several available commercial feeds) for comparative purposes.The following culture parameters and experimental conditions applied to all:
- 10% (v/v) bolus feeds on days 1, 3, and 5
- Two (2) replicates per condition
- Shake flask cultures at 37°C, 5% CO2, 120rpm Antibody production was measured from samples taken on Day 13 and when viability <75%.
