 Electrophoresis: The Test
Electrophoresis is not usually necessary to assess the loss of small to moderate amounts of protein due to temporary conditions, such as a urinary tract infection or an acute inflammation.
Protein electrophoresis may be ordered when a doctor is investigating symptoms that suggest multiple myeloma, such as bone pain, anemia, fatigue, unexplained fractures, and recurrent infections.
Serum protein electrophoresis may also be ordered when symptoms suggest an inflammatory condition, an autoimmune disease, an acute or chronic infection, a kidney or liver disorder, or a protein-losing condition, even if the total protein and/or albumin concentrations are apparently normal.

Serum serum protein electrophoresis is a laboratory examination that commonly is used to identify patients with multiple myeloma and other disorders of protein.

 ► Protein electrophoresis - serum
Protein electrophoresis - serum is a test that roughly quantitates the various protein fractions in serum (see also immunoelectrophoresis - serum; immunofixation - serum; serum globulin electrophoresis).
Proteins are important constituents of all cells and tissues.
Serum proteins are grossly separated into albumin and globulins, i.e., total protein = albumin + globulin.

Once the diagnosis of CIDP was made, serum protein electrophoresis was performed to evaluate for monoclonal gammopathy.
Immunofixation electrophoresis (Figure 2) was performed to further characterize the band.
The serum sample used to perform the electrophoresis procedures was visually examined, and fine filamentous yellow precipitate was observed in the serum sample.

 Total Serum Protein
A total serum protein test measures the total amount of protein in blood serum as well as the amounts of albumin and globulin.
An increase in serum globulin can indicate a rare type of blood cancer called multiple myeloma, leukemia, an autoimmune disease (such as rheumatoid arthritis, systemic lupus erythematosus, or autoimmune hepatitis), kidney disease, liver disease, a chronic infection (such as tuberculosis), hemolytic anemia, sarcoidosis, or severe dehydration.
If the results of the total serum protein test are abnormal (especially the globulin levels), another test called serum protein electrophoresis is often done.

 Electrophoresis: The Test Sample   (Site not responding. Last check: 2007-09-10)
Protein electrophoresis is a method for separating the proteins found in blood (serum) or urine.
These separated proteins may be detected by the use of a dye that binds to (stains) all of the proteins and reveals a characteristic pattern of bands.
In contrast to other proteins in serum, which are typically of a single type, antibodies (immunoglobulins) must differ from each other to be able to recognise bacteria, viruses and other 'foreign' substances.

 Serum Protein Electrophoresis (SPE) - [Medical Test]
Proteins are substances made up of smaller building blocks called amino acids.
Proteins carry a positive or a negative electrical charge, and they move in fluid when placed in an electrical field.
Serum protein electrophoresis uses an electrical field to separate the proteins in the blood serum into groups of similar size, shape, and charge.

In the majority of patients with myeloma, SPE is useful for diagnosis usually demonstrating a monoclonal protein, associated hypogammaglobulinemia or both.

 Serum Protein Electrophoresis (SPE)
Serum protein electrophoresis is most often done to screen for multiple myeloma, a rare type of cancer that causes overproduction of a type of the antibody IgM (Waldenstrom's macroglobulinemia), or a disease that causes an abnormal buildup of protein in various body organs (amyloidosis).
Although abnormal protein levels may be found in many conditions (such as kidney disease, chronic liver disease, systemic lupus erythematosus, rheumatoid arthritis, or leprosy), serum protein electrophoresis is not done to diagnose these conditions.
Serum protein electrophoresis may be done to evaluate hypogammaglobulinemia (HGG), a condition characterized by low levels of gamma globulin antibodies.

 Serum Protein Electrophoresis (SPE) What To Think About, Eastern Carolina
Electrophoresis on protein in urine may also be done, especially if the results of the serum protein electrophoresis test are abnormal.
Normally very little protein is found in urine, but certain diseases (such as multiple myeloma) cause large amounts of protein to leak into the urine.
Although abnormal protein levels may be found in many conditions (such as kidney disease, chronic liver disease, systemic lupus erythematosus, rheumatoid arthritis, or leprosy), serum protein electrophoresis is usually not done to diagnose these conditions.

 Multiple Myeloma
The frequency of the various immunoglobulin types of MM parallels the serum concentrations of those Igs: IgG in 60% to 70%, IgA in 20%, and light chain in only 15%; few cases of IgD and IgE have been reported, and approximately 1% of patients are nonsecretors.
A monoclonal protein (M-protein) is usually seen as a narrow peak (like a church spire) in the densitometer tracing.
Features of MM that distinguish it from MGUS include greater concentrations of serum and urine M proteins, increased percentage of bone marrow plasma cells, higher plasma cell label-ing index, the presence of lytic bone lesions, and the presence of circulating plasma cells in the peripheral blood.

Serum samples are injected into a narrow-bore capillary tube and the protein fractions are separated in a liquid phase buffer by the application of high voltage across the capillary.
The typing of the monoclonal component is determined by overlaying SPE electropherograms from before and after incubation with antisera to visually determine which heavy and light chain antisera has removed the monoclonal protein (immunosubtraction) from the serum.
The immunosubtraction indicates the monoclonal protein is IgG Kappa.

 Protein electrophoresis - Wikipedia, the free encyclopedia
In chemistry and medicine, protein electrophoresis is a method of analysing a mixture of proteins by means of gel electrophoresis, mainly in blood serum (blood plasma is not suitable).
There are two large classes of blood proteins: albumin and globulin.
They are generally equal in proportion, but albumin is much smaller and lightly negatively charged, leading to an accumulation of albumin on the electrophoretic gel.

 Final Diagnosis -- Case 390
The position of the band and the observation of material in the serum raised the possibility that fibrinogen was the band in the gamma region on serum protein electrophoresis.
Fibrinogen is not normally seen in serum but if present would appear in serum electrophoresis as a distinct band between the β- and γ-globulins.
If the immunofixation had not been performed and only protein electrophoresis reported, it is possible that this patient would have been evaluated for a monoclonal protein that did not exist.

 SERUM PROTEINS
Serum protein electrophoresis is generally performed to identify patients who have paraproteins.
This is a single protein involved in the transport of thyroid hormones and vitamin A derivatives, worth mentioning because it migrates on the far side of albumin (hence the misleading old name "prealbumin").
It is usually not visible on routine serum protein electrophoresis, but measuring it by a separate assay is usable as an indicator of general health.

 Dr. Schilling's Net Health Book - Multiple Myeloma
The serum M protein on serum protein electrophoresis is very suggestive of multiple myeloma.
The overall survival is 2.5 to 3 years, but depending on the extent of the disease at diagnosis this can be modified significantly, in some cases with survivals of up to 10 to 20 years.
Generally speaking poor prognostic indicators at the time of the initial diagnosis are: high levels of M protein in serum or urine, diffuse bone lesions, anemia, high blood calcium levels and renal failure.

 UpToDate Recognition of monoclonal proteins
Analysis of serum or urine to detect the presence of an M-protein and identify it according to its heavy chain class and light chain type requires a sensitive, rapid, and dependable screening method [1].
— Analysis of serum for the presence of M-proteins is classically performed using electrophoretic techniques, supplemented with additional tests for protein quantification and methodologies to determine whether the protein arises from a single clone (ie, monoclonal).
In the electrophoretic methodologies, proteins are classified by their final position after electrophoresis is complete into five general regions: albumin, alpha-1, alpha-2, beta, and gamma (show figure 1).
