Waymouth’s MB 752/1 Culture Medium

Waymouth’s MB 752/1 culture medium is a chemically defined medium developed by Charity Waymouth, which was originally used to study the nutritional, metabolic and growth characteristics of mouse L subcell line L929 cells under serum-free conditions.


Waymouth’s MB 752/1 culture medium has now been extended for the culture of intact organs as well as many other cell lines, such as cancer cells.

L-glutamine (Glutamine)

L-glutamine (Glutamine) is an essential nutrient element in cell culture, but it is unstable in solution and will degrade spontaneously. The amount of L-glutamine can be arbitrarily adjusted according to the research needs of the medium without L-glutamine, and the addition of fresh L-glutamine or its substitutes at the time of use is more beneficial to the cell growth.

L-alanyl-L-glutamine (Ala-Glu), also known as alanyl-glutamine and alanyl-glutamyl dipeptide, is an advanced cell culture additive that can directly replace L-glutamine in the cell culture medium. l-Glutamine is an essential nutrient in cell culture, but it is unstable in solution and will, however, it is unstable in solution and spontaneously degrades to produce ammonia and pyroglutamic acid, of which ammonia is harmful to cells, whereas L-alanyl-L-glutamine is very stable in aqueous solution and does not degrade spontaneously. The mechanism of cellular utilization is that during cell culture, cells will gradually release a peptidase into the culture medium to hydrolyze L-alanyl-L-glutamyl into L-alanine and L-glutamine, and then cells will take up and utilize these two hydrolysis products. The process of cellular utilization of L-alanyl-L-glutamyl is similar to the flow-addition culture strategy, in that low levels of L-glutamine are continuously added to the culture medium, thereby increasing the utilization of L-glutamine without generating excess ammonia, which is more conducive to cell growth. L-alanyl-L-glutamyl can replace equimolar L-glutamine, is suitable for all cells, requires little adaptation, and can extend the cell culture time. It can also extend the cell culture time and reduce the number of passages, which saves time and money. Cells cultured in medium supplemented with L-glutamine showed a slower reduction in activity than those cultured in a medium supplemented with L-glutamine. The slightly longer delay period is due to the time required for the release of peptidase and digestion of the dipeptide.


HEPES is an excellent biological buffer, which has no toxic effect on cells. The medium with HEPES can maintain a constant pH range for a longer period of time, which can effectively prevent the cell growth from being adversely affected by large pH fluctuations of the culture medium. It can be used in CO2-free incubators.
