Dulbecco's Modified Eagle's Medium (DMEM) - Modification 15

Dulbecco's Modified Eagle's Medium (DMEM) - Modification 15 containing high glucose and L-glutamine, but not containing sodium pyruvate or sodium bicarbonate, is a specialized formulation widely utilized in cell culture due to its tailored nutrient profile. This medium provides a high concentration of glucose, serving as a vital energy source, particularly beneficial for rapidly proliferating cells and those requiring high metabolic activity. The inclusion of L-glutamine, an essential amino acid, supports protein synthesis and cellular metabolism, ensuring optimal growth and viability of cultured cells.

The absence of sodium pyruvate in this DMEM (Modification 15) is advantageous for specific experimental setups where the presence of pyruvate could interfere with metabolic studies or cellular processes under investigation. Similarly, the exclusion of sodium bicarbonate allows for precise pH control, especially in closed systems or during transport where CO2 levels cannot be regulated. This makes the medium highly adaptable for a variety of research conditions and applications.

Key applications of DMEM - Modification 15 include:

• Metabolic Studies: Ideal for experiments focusing on cellular metabolism without the confounding effects of pyruvate.
• Transport and Storage: Suitable for use in conditions where CO2 regulation is not feasible, maintaining stable pH levels.
• Protein Expression: Supports high-density cell cultures for the production of recombinant proteins.
• Cancer Research: Facilitates the growth of cancer cell lines that exhibit high metabolic rates.
• Stem Cell Culture: Provides a nutrient-rich environment for the proliferation and differentiation of various stem cell types.

Disclaimer: Results may vary depending on specific cell lines, specifications, and experimental conditions. Consult with cell culture specialists and review comprehensive literature to tailor its use to your specific research needs.
