Ham's F-12 Nutrient Mixture (F-12) was designed for serum-free single-cell plating of Chinese Hamster Ovary (CHO) cells. F-12 has since been used for serum-free growth of CHO cultures as well as serum-supplemented growth of other mammalian cells, including chondrocytes and rat prostate epithelial cells. We offer a variety of Gibco™ F-12 modifications for a range of cell culture applications. Find the right formulation using the media selector tool.


This Ham's F-12 is modified as follows:
WithWithout
• L-glutamine• Sodium Bicarbonate
• Phenol Red 


The complete formulation is available.

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 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. Powder forms of Gibco™ cell culture medium require sodium bicarbonate supplementation, pH adjustment, and filtration at the time of preparation (see protocol for details).

Not for human or animal therapeutic use. Uses other than the intended use may be a violation of local law. For in vitro diagnostic use.

Frequently asked questions (FAQs)

What is the shelf life of my powdered media once I reconstitute it?

Expiration date of most Gibco reconstituted dry format media (AGT or DPM) has not been established; end users should assess performance and stability of this reconstituted media in a system that is relevant to their process. A dry format product (either DPM or AGT) will age upon storage and while we may not be able to detect which component(s) degrade since we can't measure every component, that doesn't mean that the reconstituted liquid will have the same stability as a fresh liquid made by direct weigh methods.

How long can I keep my media after supplementing with serum?

Generally speaking, media can be used for up to three weeks after supplementation with serum. There are no formal studies to support this, but it is the rule of thumb used by our scientists.

My medium was shipped at room temperature but it is supposed to be stored refrigerated. Is it okay?

We routinely ship media that require long-term storage in the refrigerator at room temperature. We have done studies on representative media formulations to show that media can be at room temperature for up to a week without a problem.

How can I remove mycoplasma contamination from my cell culture medium?

Very often mycoplasma contamination cannot be removed from the culture so it should be discarded. You may have a unique culture that you prefer not to discard and would like to try to clean it. Ciprofloxacin and Plasmocin have reportedly been used for this application. If interested in a protocol or directions for use, check with the antibiotic supplier or published literature. Note that mycoplasma are very difficult to remove from culture and spread easily so the treated cultures should be quarantined until clear of mycoplasma, and your laboratory should be thoroughly cleaned.

I see a decrease in growth of my culture. What should I do?

Try changing the medium or serum. Compare media formulations for differences in glucose, amino acids, and other components. Compare an old lot of serum with a new lot. Increase initial cell inoculums. Lastly, adapt cells sequentially to new medium.
