摘　　要：近年来，基因工程技术的迅速发展，大量有价值的蛋白质在大肠杆菌中获得了高表达。多种表达系统的完善与发展，及蛋白质分离纯化技术的提高，异源蛋白的产量与纯度已不再是困扰人们的主要问题，人们开始更多地关注异源蛋白的活性，比活性及异源蛋白的正确性，完整性。随着这些问题的解决。In recent years,along with the rapid development of genetic engineering technoligies,a vast amount of valuable proteins have been expressed in E.coli with high productivity. The problems concerning the productivity and purity of the heterologous proteins are no longer the major ones,as many expression system and protein purification schemes have been developed and perfected.More attention is being payed to the activity,specific activity,correct folding and intactness of the heterologous proteins.Perhaps it is the solutions to such problems that will finally lead to the maturity of the application of recombinant proteins.
