应用
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。

A novel neutrophil chemoattractant derived from collagen, proline-glycine-proline (PGP), has been recently characterized in chronic obstructive pulmonary disease (COPD). This peptide is derived via the proteolytic activity of matrix metalloproteases (MMP's)-8/9 and PE, enzymes produced by neutrophils and present in

Despite the abundance of membrane-associated enzymes, the mechanism by which membrane binding stabilizes these enzymes and stimulates their catalysis remains largely unknown. Serum paraoxonase-1 (PON1) is a lipophilic lactonase whose stability and enzymatic activity are dramatically stimulated when associated with
