Abstract
Heparin and heparan sulfate (HS) may be purified from complex biological matrices and are often isolated in sub-milligram quantities but not unequivocally identified by spectroscopic means. This protocol details a methodology to rapidly assess the gross compositional features and approximate purity of HS by 1H nuclear magnetic resonance. A complimentary method for identification and characterisation of heparan sulfate can be found at Carnachan and Hinkley (2017).
