DMF (dimethylformamide) is a recommended solvent for labeling reactions using NHS esters. However, when DMF is stored in air, it deteriorates slowly absorbing moisture, and releasing dimethylamine. These impurities rapidly destroy NHS ester function, decrease labeling efficiency, and even make labeling reaction fail.

Dimethylformamide solvent requires special drying and preparation, which is often not available in all laboratories.

This product contains ready-to use solvent which is guaranteed to be useable for the labeling. Tubes with high quality, dry, and amine-free DMF are packed under argon.

DMF(二甲基甲酰胺)是使用 NHS 酯标记反应的推荐溶剂。 然而,当 DMF 储存在空气中时,它会吸收水分缓慢变质,并释放出二甲胺。 这些杂质迅速破坏NHS酯功能,降低标记效率,甚至使标记反应失败。


本产品含有即用型溶剂,保证可用于标签。 具有高质量、干燥和无胺 DMF 的管子在氩气下包装。
