A biologically active complex of lactoferrin with a branched non-peptide hydrophilic polymer, one example of which is represented by the following formula [1]:n nLF-[X-L p -R—(Y p -POLY) q ] n   [I]n nWherein LF is lactoferrin, X is a linkage generated by reaction of functional groups, L is a linker, R is an aliphatic hydrocarbon group having at least 3 carbon atoms, Y is a heteroatom linkage, POLY is a non-peptide hydrophilic polymer, p is 0 or 1, q is an integer of 2 to 10, and n is an integer of 1 to 10. |
