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.
