To obtain the anti-transferrin receptor scFv and streptavidin(SA) recombinantfusionproteins which were high-efficiently and solubly expressed in E.
拟获得在大肠杆菌中能高效可溶表达的转铁蛋白受体单链抗体与链亲和素（SA）的重组融合蛋白。

Conclusion The recombinant GST-3C protease can be not only applied to the cleavage of fusionproteins, but also be used as a tool-enzyme in TAP system containing 3C recognition sequence.
The strategies of fusion protein designing and its advantages and disadvantages in the bioprocessing of recombinantproteins, were introduced in this article.
