'metalloprotein and process for its production, and prophylactic or therapeutic people for corneal and conjunctival diseases comprising said metalloprotein'

摘要

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.
