摘要 综述了包涵体形成、包涵体分离和溶解、包涵体折叠复性的方法、复性产率低下的主要因素以及通过分子伴侣、低分子量添加物等的应用而提高了蛋白质复性产率。关键词 包涵体 蛋白质 复性Abstract Strategies for decreasing the formation of inclusion bodies, isolation and resolution of inclusion bodies, refolding of inclusion body proteins and the cause of decreased refolding yields were included. Renaturation yield of recombinant protein have been improved by using some additives, such as molecular chaperone, small molecules.Key words inclusion body , protein , renaturation 外源基因在大肠杆菌中的高表达常常导致包涵体的形成，虽然包涵体具有富集目标蛋白质、抗蛋白酶、对宿主毒性小等优点，但包涵体蛋白质的复性率一般都很低,而分子伴侣、
