Glycosylated albumin as a drug carrier for a DDS targeting the liver (particularly kupffer's cell) can be provided by mutating a DNA encoding albumin to encode a mutant albumin containing a partial amino acid sequence permitting glycosylation modification by eukaryotic cell, preferably a consensus sequence of N-linked sugar chain, introducing an expression vector containing the mutant DNA into a host eukaryotic cell, preferably a host cell permitting addition of a high-mannose type sugar chain, culturing the obtained transformant, and recovering a glycosylated albumin protein from the obtained culture.
