Document Type and Number:
WIPO Patent Application WO/2005/049857
Kind Code:
A1
Abstract:
It is intended to provide a method of conveniently and efficiently assaying a glycoprotein, a fructosyl peptide or a fructosyl amino acid while lessening the effects of fructosyl lysines and an assay reagent. A method of lessening the effects of fructosyl lysines in assaying a fructosyl peptide or a fructosyl amino acid in a sample, characterized by comprising specifically treating the fructosyl peptide or the fructosyl amino acid with an enzyme for assaying the fructosyl peptide or the fructosyl amino acid at pH 4.0 to 7.0 and assaying the obtained product at pH 4.0 to 7.0; and a method of assaying a glycoprotein by using the same.
