Association of Fibronectin With Hypogalactosylated Immunoglobulin G in Gingival Crevicular Fluid in Periodontitis

Abstract

IgG and the FN fragment of 48 to 53 kDa in GCF of periodontitis patients and periodontally healthy subjects are physically connected. This fragment was linked to the heavy chains of IgG and the reaction seemed to be particularly intensive with IgG from advanced periodontitis, which contained significantly less galactose in its sugar chains.
