abstract |
The present invention relates to a novel use of an immunoglobulin Fc region, and more specifically to a pharmaceutical composition comprising an immunoglobulin Fc region as a carrier. A pharmaceutical composition comprising an immunoglobulin Fc region as a drug carrier significantly increases the blood half-life while maintaining a relatively high in vivo activity of the drug to be bound. In addition, when the drug is a polypeptide drug, the risk of inducing an immune response is less than that of a fusion protein of an immunoglobulin Fc region and a target protein, and the drug can be usefully used for the development of continuous preparations of various polypeptide drugs. |
