Differential glycan profiles of purified IgA1 after trypsin digestion.

<p>IgA1 purified from sera of three HVs, two MPCD patients, and one mIgA-MIDD patient was incubated with trypsin. Each tryptic digest was labeled with Cy3-SE and subjected to the lectin microarray. The relative intensities of lectins were normalized to the maximum fluorescence intensity.</p

Differential glycan profiles of purified IgA1.

<p>IgA1 purified from sera of three HVs, two MPCD patients, and one mIgA-MIDD patient was subjected to lectin microarray. IgA1-binding signals on the lectin microarray were detected with a biotinylated anti-IgA1 mAb. The relative intensity of each lectin was normalized to the maximum fluorescence intensity. mIgA-MIDD, monoclonal immunoglobulin deposition disease associated with monoclonal IgA; MPCD, monoclonal IgA plasma cell disorder; HV, healthy volunteers.</p

SDS-agarose gel electrophoresis of purified IgA1.

<p>IgA1 purified from sera of two HV, two MPCD patients, and an mIgA-MIDD patient was incubated in SDS buffer and then subjected to agarose gel electrophoresis analysis.</p
