<p>IgA1 purified from mIgA-MIDD serum was incubated with (left) or without (right) PNGase F. After digestion, the reaction mixture was labeled with Cy3-SE and subjected to the lectin microarray. The relative intensity of each lectin was normalized to the maximum fluorescence intensity. mIgA-MIDD, monoclonal immunoglobulin deposition disease associated with monoclonal IgA; PNGase F, peptide N-glycosidase F.</p
