William's E Medium was originally developed by Williams and Gunn as reduced serum-supplemented medium for long-term cell cultures of adult rat liver epithelial cells. This media can also be used for growing hepatocyte cells of different species, such as human HepaRG™ cells.
This William's E Medium is modified as follows:
WithWithout
• Phenol Red• L-glutamine
• HEPES

The complete formulation is available.

Gibco™ William's E Medium is a modification of earlier media that has been enriched in amino acids and double the glucose. William's E Medium contains unique ingredients, including zinc, iron, manganese, non-essential amino acids, the reducing agent glutathione and the lipid methyl linoleate.

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

Dual-Site cGMP Manufacturing
Gibco™ William's E Medium is manufactured at a cGMP compliant facility, located in Grand Island, New York. The facility is registered with the FDA as a medical device manufacturer and is certified to ISO 13485 standards. For supply chain continuity, we offer an identical Gibco™ William's E Medium product made in our Scotland facility (22551-022). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standard.

William's E Medium contains no proteins or growth factors. Therefore, William's E Medium requires supplementation, commonly with 5-10% Fetal Bovine Serum (FBS). William's E Medium uses a sodium bicarbonate buffer system (2.2 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.

This product is not used for in vitro diagnostic purpose in some countries.

자주 묻는 질문(FAQ)

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.

My cells are not adhering to the culture vessel. What should I do?

This can occur if cells are overly trypsinized. Trypsinize for a shorter time or use less trypsin. Mycoplasma contamination could also cause this problem. Segregate your culture and test for mycoplasma infection. Lastly, check for attachment factors in the medium.
