Serum protein electrophoresis showing a paraprotein (spike/peak in the gamma zone) in a patient with multiple myeloma.. A myeloma protein is an abnormal antibody (immunoglobulin) or (more often) a fragment thereof, such as an immunoglobulin light chain, that is produced in excess by an abnormal monoclonal proliferation of plasma cells, typically in multiple myeloma or Monoclonal gammopathy of ...
Scientists identified the protein during investigations on the origin of multiple myeloma, a type of B-cell carcinoma. To understand the long-term M. genitalium infection, Rajesh Grover, a senior staff scientist in the Lerner laboratory, tested antibodies from the blood samples of patients with multiple myeloma against different Mycoplasma species.
Being asymptomatic, monoclonal gammopathy of undetermined significance and smoldering multiple myeloma are typically diagnosed fortuitously by detecting a myeloma protein on serum protein electrophoresis tests done for other purposes. MGUS is a relatively stable condition afflicting 3% of people aged 50 and 5% of people aged 70; it progresses ...
The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma, a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy between a low albumin and a relatively high total protein.

Myeloma protein, also called paraprotein, an abnormal protein in the urine or blood, often seen in multiple myeloma or monoclonal gammopathy of undetermined significance; MYOM2 (Myomesin-2), a protein composing the M-line of muscle cell sarcomeres; Protein M, immunoglobulin-binding protein found on the surface of the bacterium Mycoplasma genitalium
Freezer Storage Tips. Since it extends the life of perishable items by weeks to months, “freezer storage is an amazing way to reduce food waste,” explains Gangeri.
Targets: M-protein levels in blood, patient-specific assays for immunoglobulin and T cell receptor genes (high levels of somatic hypermutation often prevent this assay from reliably working). Uses: M-protein level in the blood is standard of care and is used for almost all patients with multiple myeloma. Patient-specific assays are still ...
