METHOD FOR IMPROVING SOLUBILITY OF PROTEIN AND PEPTIDE BY USING IMMUNOGLOBULIN FC FRAGMENT LINKAGE.

摘要

The present invention relates to: a method for improving the solubility of a physiologically active protein or peptide, compared to a physiologically active protein or peptide to which an immunoglobulin Fc fragment is not linked, comprising a step of linking the physiologically active protein or peptide to the immunoglobulin Fc fragment; and a composition for improving the solubility of a physiologically active protein or peptide, containing an immunoglobulin Fc fragment and exhibiting improved solubility compared with that of a composition not containing the immunoglobulin Fc fragment.
