Sulfated glycoproteins in the acquired pellicle and in plaque from Macaca fascicularis demonstrated with labeled sulfate

abstract – A sulfated glycoprotein was demonstrated in 2-h pellicle material collected from monkeys. Furthermore, a sulfated macromolecule present in plaque extracts was identified as a sulfate glycoprotein by electrophoresis on cellulose acetate strips. The present data indicate that acidic proteins are selectively adsorbed to tooth surfaces in. vivo .
