Mucus glycoprotein of human saliva: differences in the associated and covalently bound lipids with caries.


A high molecular weight mucus glycoprotein has been isolated from submandibular saliva of caries-resistant and caries-susceptible individuals by a procedure involving fractionation on Bio-Gel P-100 and A-50 columns followed by equilibrium density-gradient centrifugation in CsCl. The purified caries-resistant mucus glycoprotein displayed a buoyant density of… (More)
