MES-Natriumsalz (Natrium-2-Morpholinoethansulfonat) ist eine zwitterionische N-substituierte Aminosulfonsäure, die als Good-Puffer bekannt ist und im pH-Bereich 6-8 mit einem pKa-Wert von 6,10 bei 25°C aktiv ist. Mit einem pKa-Wert nahe dem physiologischen pH-Wert wird sie nicht durch Zellmembranen absorbiert und ist im Wesentlichen transparent für UV-Licht. MES wird als Laufpuffer für die Auflösung von sehr kleinen Proteinen (z. B. 13 kDa) auf Bis-tris-Gelen verwendet. Es wird auch in der Kationenaustauschchromatographie und als biologischer Puffer in Pflanzenzellkulturen verwendet. MES-Lösungen können auf den gewünschten pH-Wert eingestellt werden, indem die freie Säure mit Natriumhydroxid titriert wird.
Ein Puffermittel, das in der biologischen und biochemischen Forschung einschließlich der Pflanzenzellkultur verwendet wird.
