13050	DMF (dimethylformamide), labeling grade, 1 mL	490.00

 

---

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.
