Waymouth's is a chemically defined medium developed by Charity Waymouth and originally formulated for studies on the nutrition, metabolism, and growth of mouse Strain L sublines, NCTC clone 929 (L929 cells) in a serum-free environment. Waymouth's medium is also used for the culture of whole organs and a broad range of cell types, such as carcinoma cell lines.

This Waymouth's medium is modified as follows:
WithWithout
• L-glutamine• HEPES
• Phenol Red 


The complete formulation is available.

Frequently asked questions (FAQs)

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.

Abstract
Ets-1 positively regulates Fas ligand transcription via cooperative interactions with Sp1.
Authors:Kavurma MM, Bobryshev Y, Khachigian LM,
Journal:J Biol Chem
PubMed ID:11970950
'The FasL/Fas system has been implicated in smooth muscle cell apoptosis and atherosclerotic plaque instability, a process that can lead to plaque rupture, precipitating myocardial infarction and sudden death. The transcriptional mechanisms regulating FasL gene expression in vascular smooth muscle cells are poorly understood. We recently described a novel mechanism ... More

'The present study tests the hypothesis that the unique intracellular third loop domain of angiotensin II type-2 (AT2) receptor is essential for the subsequent intracellular signaling and plays an important role in mediating receptor function.
