| 摘要 |
A method of producing a polyethylene glycolated (PEGylated) lactoferrin complex having a linear polyethylene glycol (PEG) or a modified product thereof covalently bonded to lactoferrin via an amide bond includes causing a reaction to occur in a reaction liquid, which contains the lactoferrin and a linear PEG derivative having a para-nitrophenol leaving group, under conditions that allow formation of an amide group between the PEG derivative and the lactoferrin. A PEGylated lactoferrin complex contains a linear PEG or a modified product thereof covalently bonded to lactoferrin via an amide bond, and a pharmaceutical composition includes a PEGlyated lactoferrin complex, a therapeutically inert base, and/or an additive.
