Product Overview
MES (2-(N-morpholino)ethanesulfonic acid) sodium salt is a zwitterionic buffer widely used in biochemical and molecular biology applications due to its excellent pH stability in the range of 5.5–6.7. This purified-grade variant ensures minimal impurities, making it ideal for sensitive experiments where consistency is critical. The sodium salt form enhances solubility in aqueous solutions, eliminating the need for pH adjustments with strong acids or bases. Its low toxicity and non-reactivity with most biological systems further enhance its utility in protein purification, cell culture, and enzymatic reactions. The powdered form allows for easy storage and precise weighing, while its resistance to metal ion chelation ensures compatibility with a broad range of lab protocols. Whether used in electrophoresis, chromatography, or general buffering, this MES sodium salt delivers reliable performance without interfering with downstream applications. The 500 g pack size provides ample quantity for high-throughput labs while maintaining cost efficiency for smaller-scale research.
FAQs
1. What is the ideal pH range for MES sodium salt buffering?
MES sodium salt is most effective as a buffer between pH 5.5 and 6.7, making it suitable for slightly acidic conditions in biochemical assays.
2. Can this MES sodium salt be used with divalent cations like magnesium or calcium?
Yes, MES has minimal chelating properties, so it does not significantly bind divalent cations, allowing its use in reactions requiring magnesium or calcium ions.
3. How should MES sodium salt be stored for long-term stability?
Store the powder in a cool, dry place, sealed in its original container to prevent moisture absorption. Avoid exposure to direct sunlight or high humidity.
4. Is this purified grade suitable for cell culture applications?
Yes, the purified grade is low in endotoxins and contaminants, making it compatible with cell culture media where buffer purity is essential.
5. What alternatives exist if MES is not suitable for my experiment?
For pH ranges outside 5.5–6.7, consider HEPES (pH 6.8–8.2) or acetate buffers (pH 3.6–5.6) depending on your specific requirements.
