We glycated immunoglobulins from commercial kits designed to measure human ferritin, thyrotropin, and transferrin, and compared the calibration curves for assays utilizing glycated antibodies with those of assays utilizing non-glycated antibodies. Glycation was verified by borate affinity chromatography and assay with thiobarbituric acid reagent. We found no evidence that antigen-antibody binding is impaired by nonenzymatic glycation of antibodies. Our results provide no evidence in support of the supposition that glycation may be a contributory factor in the decreased resistance of diabetics to infection.
