NOVEL METALLOPROTEIN AND PROCESS FOR PRODUCING SAME, AND PROPHYLACTIC OR THERAPEUTIC AGENT FOR CORNEAL AND CONJUNCTIVAL DISEASES COMPRISING SAID METALLOPROTEIN
The present invention provides: a novel metalloprotein, i.e., selenium-lactoferrin and a process for producing the metalloprotein. Selenium-lactoferrin according to the present invention can be produced suitably by adding a selenium salt to a solution containing lactoferrin and/or apolactoferrin and then subjecting the resultant mixed solution to dialysis or ultrafiltration.Selenium-lactoferrin according to the present invention has an excellent therapeutic effect on corneal and conjunctival diseases, and is suitable for mass production on an industrial scale.
