Product Overview
MES sodium salt (99% purity) is a zwitterionic buffering agent widely used in biochemical and molecular biology applications due to its excellent pH stability in the range of 5.5–6.7. This high-grade powder is highly soluble in water, forming clear, colorless solutions that resist metal ion chelation, making it ideal for sensitive assays. Its low toxicity and minimal interference with biological systems ensure reliable results in protein purification, cell culture, and electrophoresis. The sodium salt form enhances solubility compared to free acid, allowing for precise buffer concentration adjustments without pH drift. Designed for researchers requiring consistent performance, this MES variant maintains integrity across temperature fluctuations and extended storage periods. Its non-volatile nature prevents evaporation losses during prolonged experiments, while the absence of UV absorbance ensures compatibility with spectrophotometric analyses. Whether used in enzyme reactions or as a stabilizing agent, this 99% pure MES sodium salt delivers reproducibility in critical laboratory workflows.
FAQs
1. What is the ideal pH range for MES sodium salt buffers?
MES sodium salt functions optimally between pH 5.5 and 6.7, making it suitable for slightly acidic applications.
2. Can this MES salt be used with divalent cations like calcium or magnesium?
Yes, MES has minimal chelation properties, allowing it to work effectively in solutions containing divalent metal ions.
3. How should MES sodium salt be stored for long-term stability?
Store in a cool, dry place in a tightly sealed container to prevent moisture absorption and maintain purity.
4. Is this MES variant compatible with cell culture media?
Yes, its low cytotoxicity and stable buffering capacity make it suitable for cell culture applications.
5. What alternatives exist if MES is unavailable for my experiment?
PIPES or MOPS buffers can serve as alternatives, though their pH ranges differ slightly (PIPES: 6.1–7.5, MOPS: 6.5–7.9).
