Abstract
GAGs were purified from urine of dogs after intranasal administration of 40 mg/kg ITF 1300. The electrophoretic patterns of urine GAGs in acidic buffer showed the presence of heparin together with chondroitins, heparan sulfate, and hyaluronic acid. The heparin present in urines was purified using chondroitinase ABC, and its purity was tested by electrophoresis in acidic buffer. The sample obtained was characterized by 13C-NMR, showing the same characteristic signals of the heparin starting material.
