Composition for stabilizing a fusion protein in which a protein and an Fc domain are fused

摘要

The present invention relates to a composition for stabilizing a fusion protein of a physiologically active protein and an Fc domain, and uses an ammonium salt or a composition containing an ammonium salt and a succinate to make a protein and Fc domain. The present invention relates to a method for stabilizing a fusion protein. Since the composition containing an ammonium salt or an ammonium salt and succinate according to the present invention effectively inhibits the aggregation of the Fc-fusion protein, the fusion protein can be stored for a long time. It can be widely used in the medical field using fusion proteins.
