Abstract

The purpose of the present invention is to develop: a method for selectively separating a glycoprotein derived from the central nervous system from a body fluid or a central nervous system cell; and a method for searching for an index marker for central nervous system diseases, which utilizes the aforementioned method. A protein derived from the central nervous system, which occurs in a trace amount in a body fluid or a central nervous system cell, can be selectively enriched by a two-stage separation procedure comprising removing a glycoprotein having sialic acid at a non-reducing terminal thereof from the body fluid or the central nervous system cell and then separating a glycoprotein having N-acetylglucosamine at a non-reducing terminal thereof.
