Compared to other basal media, F-12 contains a wider variety of components, including zinc, putrescine, hypoxanthine, and thymidine. Serum-free growth of CHO cells in F-12 has led to a variety of improved formulations. Gibco F-12 with GlutaMAX supplement minimizes toxic ammonia build-up and improves cell viability and growth in an easy-to-use format.

Using Ham's F-12 Nutrient Mixture：
Gibco F-12 contains no proteins or growth factors. Therefore, F-12 requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). F-12 uses a sodium bicarbonate buffer system (1.176 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.

cGMP Manufacturing and Quality System：
For supply chain continuity, we manufacture Gibco F-12 at two separate facilities located in Grand Island, NY and Scotland, UK. Both sites are compliant with cGMP manufacturing requirements, are certified to ISO 13485, and are registered with the FDA as medical device manufacturers.
