Neuropathy and IgM paraproteinemia: differential binding of IgM M-proteins to peripheral nerve glycolipids.
Two patients with neuropathy and IgM paraproteinemia displayed different immunoreactivity to acidic peripheral nerve glycolipids. In one patient, immunostaining on thin-layer chromatographic plate revealed binding of the IgM to sulfated glucuronosyl paragloboside (SGPG) and sulfated glucuronosyl lactosaminyl paragloboside (SGLPG). The other IgM bound SGPG, SGLPG, and a new third glycolipid. Immunoreactivity of the IgM varies in this syndrome.
