Sensitivity of immunofixation electrophoresis for detecting IgM paraproteins in serum.
Detection and characterization of small IgM paraproteins by immunoelectrophoresis are often difficult because of (a) slow diffusion of the macromolecular immunoglobulin, and (b) the obscuring of the light chain, especially kappa, by the light chains of background polyclonal immunoglobulin (the "umbrella effect"). Various methods of sample pretreatment have been tried in an attempt to overcome t...
متن کاملHuman IgM paraproteins demonstrate shared reactivity between Campylobacter jejuni lipopolysaccharides and human peripheral nerve disialylated gangliosides.
IgM paraproteins from patients with CANOMAD (chronic ataxic neuropathy, ophthalmoplegia, M-protein, agglutination, anti-disialosyl antibodies) react with NeuAc(alpha 2-8)NeuAc epitopes on a wide range of gangliosides including GQ1b, GT1a, GD1b and GD3. The tissue distribution of reactive antigens in human peripheral nerve has not been addressed in detail. In addition, the origin of these antibo...
متن کاملStructure of sulfated glucuronyl glycolipids in the nervous system reacting with HNK-1 antibody and some IgM paraproteins in neuropathy.
Novel sulfated glucuronic acid-containing glycolipids have been identified in the nervous system. These glycolipids are highly antigenic and share antigenic determinants with several nervous system glycoproteins, such as neural cell adhesion molecules, myelin-associated glycoprotein, and ependymins. The structure of the major antigenic glycolipid from human peripheral nerve was determined by ch...
متن کاملMonomeric complement-activating IgG paraproteins.
Three patients presented a unique syndrome of recurrent panniculitis with an IgGkappa paraprotein and depletion of the early components of the classical pathway of complement. The IgGkappa paraproteins were monomers with a normal structure, and with no evidence for aggregation, as assessed by electron microscopy and ultracentrifugation. Both heavy and light chains were of normal molecular size ...
متن کاملSerum paraproteins in chronic lymphocytic leukaemia.
The presence of paraproteins in the sera of 10 patients with chronic lymphocytic leukaemia (CLL) was investigated using immunoisoelectric focusing. Monoclonal immunoglobulins were found in nine of these 10 sera. Five sera contained a single monoclonal IgM paraprotein, one serum contained a single monoclonal IgG paraprotein, while three sera contained more than one monoclonal paraprotein--namely...
