a homogeneous immunoglobulin resulting from the proliferation of a single clone of plasma cells; during electrophoresis of serum, it appears as a narrow band or "spike"; it is characterized by heavy chains of a single class and subclass and by light chains of a single type. The disorder occurs most commonly in older men. Monoclonal gammopathy of undetermined significance (MGUS) is a condition in which an abnormal protein known as monoclonal protein or M protein is in your blood. Genetic changes and environmental triggers appear to play a role. In multiple myeloma, cancerous plasma cells accumulate in the bone marrow and crowd out healthy blood cells. Sometimes, it may also occur in Hodgkin's disease. Immunofixation electrophoresis (IFE) is performed to identify the immunoglobulin heavy chain and/or light chain.
