title: Two IgM paraproteins differing in carbohydrate content in a patient with Waldenström's macroglobulinemia.
abstract: Two IgM paraproteins of different electrophoretic mobility were detected in the serum of a patient with Waldenstrom's disease. Both were type kappa, existed as high molecular weight polymers, and contained J-chain. The faster-moving protein contained a greater amount of carbohydrate, in both H and L chains.
