Disclosed is an IgG Fc fragment useful as a drug carrier. Also, the present invention discloses a recombinant vector expressing the IgG Fc fragment, a transformant transformed with the recombinant vector, and a method of preparing an IgG Fc fragment, comprising culturing the transformant. When conjugated to a certain drug, the IgG Fc fragment improves the in vivo duration of action of the drug and minimizes the in vivo activity reduction of the drug.
本发明公开了一种可用作药物载体的 IgG Fc 片段。此外,本发明还公开了一种表达该 IgG Fc 片段的重组载体、一种用该重组载体转化的转化体,以及一种制备 IgG Fc 片段的方法,包括培养该转化体。当与某种药物共轭时,IgG Fc 片段可提高药物在体内的作用时间,并最大限度地降低药物在体内的活性。
