Product type
CHO cell culture medium is a specialized nutrient solution designed to support the growth and maintenance of Chinese Hamster Ovary (CHO) cells, which are widely used in biopharmaceutical production. These media are formulated with essential nutrients, vitamins, amino acids, and growth factors to optimize cell proliferation and productivity. CHO cells are commonly utilized in the production of therapeutic proteins, monoclonal antibodies, and vaccines due to their ability to perform post-translational modifications similar to human cells.
| Base composition | Powder or liquid formulation |
| pH range | 6.8 to 7.4 |
| Osmolality | 280 to 320 mOsm/kg |
| Sterility | Sterile filtered or irradiated |
| Storage conditions | 2 to 8 degrees Celsius |
When selecting CHO cell culture medium, consider the specific requirements of your cell line and the intended application. It is important to specify the formulation type, such as whether you need a serum-free or serum-containing medium. Additionally, inquire about the pH, osmolality, and any necessary supplements or additives. Certifications for sterility and quality should also be confirmed, especially for use in regulated environments. Quantities can vary based on scale, so provide your estimated usage to receive accurate quotes.
