詳細

詳細

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

アプリケーション

Dimethyl sulfoxide is used as a solvent:

• To dissolve the substrate and to dilute fluorogenic substrate.
• To permeabilize V. natriegens or E coli cell.

注意

容易に過冷却状態となり、室温で徐々に再融解します。凝固している場合は室温に放置すると、劣化させることなく液体に戻すことができます。
