M-Clarity Program
As part of our Emprove^® Program, our raw materials are offered with Emprove^® Dossiers which provide comprehensive, up-to-date documentation to help you navigate regulatory challenges, manage risks, and improve your manufacturing processes.
Our comprehensive portfolio of downstream process chemicals not only provides biopharmaceutical manufacturers with high-quality raw materials for production of classical and novel therapies, but also helps them get to market faster and simplify regulatory challenges. Ranging from non-GMP grades for low-risk application, to IPEC-PQG GMP for higher-risk applications, we have products covering all your manufacturing needs.

應用

用于将 −SH 基保持在还原态的绝佳试剂；定量还原二硫化物。在 SDS-PAGE 前，DTT 在样品缓冲液中可有效还原蛋白二硫键。DTT 还可用于还原交联剂 N,N′-双(丙烯酰)胱胺的二硫键桥以分解聚丙烯酰胺凝胶基质。DTT 的刺激性和毒性都低于 2-巯基乙醇。通常，使用 DTT (100mM) 所需的浓度是使用 2-巯基乙醇 (5% v/v, 700mM) 的浓度的七分之一。

DTT is an excellent reagent chemical used to reduce disulfide bonds commonly found in bioprocessing. DTT is used in buffer formulations to maintain and stabilize free -SH in applications such as protein based biotherapeutics and enzyme stability.
