METHODS FOR DETECTING AND QUANTIFYING OVERSULFATED GLYCOSAMINOGLYCANS

摘要

The invention relates to novel methods for detecting and/or quantifying oversulfated or persulfated glycosaminoglycans based on inhibition of nucleic acid polymerases. The methods can be utilized to detect and quantify oversulfated or persulfated glycosaminoglycans in pharmaceutical preparations, such as heparin preparations or therapeutic medical devices. When used to detect or quantify oversulfated glycosaminoglycans in heparin containing solutions, the samples are prepared by treatment with heparinases to degrade the heparin. Titration of the inhibition of the activity of the polymerases allows quantitation of the oversulfated glycosaminoglycans in the sample.
