Medium 199 was originally developed for nutritional studies of chick embryo fibroblasts. It has broad species applicability, particularly for cultivation of non-transformed cells. Medium 199 is widely used in virology, vaccine production, and in vitro cultivation of primary explants of mouse pancreatic epithelium, and rat lens tissues. We offer a variety of Gibco™ Medium 199 modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

This M199 is modified as follows:

With: L-glutamine, Phenol Red

Without: HEPES, Sodium Bicarbonate

The complete formulation is available.

Compared to other basal media, Medium 199 contains unique components, including adenine, adenosine, hypoxanthine, thymine, and additional vitamins. Medium 199 is available with Earle's salts for use in a CO2 incubator, or with Hanks' salts for use without CO2.

Using Medium 199

Medium 199 contains no proteins, lipids, or growth factors. Medium 199 uses a sodium bicarbonate buffer system (2.2 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).

Please note that the shelf life on delivered products varies. This product has a minimum shelf life of 6 months at time of shipment. For more information regarding product shelf life, including details on specific product lots, please contact Customer Service.

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.
