Title:
METHOD FOR ANALYZING GLYCOSAMINOGLYCAN
Document Type and Number:
WIPO Patent Application WO/2018/155443
Kind Code:
A1
Abstract:
[Problem] To provide a method for measuring trace amounts of heparan sulfate and/or dermatan sulfate contained in a sample. [Solution] The present invention provides a method for decomposing heparan sulfate and dermatan sulfate contained in a sample into, respectively, a disaccharide in which uronic acid and amino sugar are α1,4-bonded and a disaccharide in which uronic acid and amino sugar are α1,3-bonded. More particularly, the present invention provides a method for decomposing heparan sulfate and dermatan sulfate by heating the heparan sulfate and the dermatan sulfate in, for example, 2,2-dimethoxypropane-containing methanol hydrochloride at 65-85°C for 80-180 minutes and 60-80°C for 20-100 minutes, respectively.
