Identification of IgA, IgG, lysozyme, albumin, alpha-amylase and glucosyltransferase in the protein layer adsorbed to hydroxyapatite from whole saliva.

IgA, IgG, albumin, lysozyme, alpha-amylase and glucosyltransferase were identified in the saliva coat which forms on hydroxyapatite exposed to whole saliva. It is suggested that these proteins may be involved in binding microorganisms to saliva coated hydroxyapatite in model studies.
