Electrophoresis is a laboratory technique in which the blood serum (the fluid portion of the blood after the blood has clotted) is applied to either an acetate membrane soaked in a liquid buffer, [3] or to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein ...
The test uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis.After the sample has been treated to release the hemoglobin from the red cells, it is introduced into a porous gel (usually made of agarose or cellulose acetate) and subjected to an electrical field, most commonly in an alkaline medium.
Normal total protein levels are not sufficient to rule out multiple myeloma or other malignant paraproteinemias, but they may also be the cause of moderate-to-marked hyperproteinemia. To determine the reason behind the elevated serum total protein, a serum protein electrophoresis should be carried out. [2] clinical significance
Monoclonal gammopathy, also known as paraproteinemia, is the presence of excessive amounts of myeloma protein or monoclonal gamma globulin in the blood. It is usually due to an underlying immunoproliferative disorder or hematologic neoplasms, especially multiple myeloma. It is sometimes considered equivalent to plasma cell dyscrasia.
Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]
Hypergammaglobulinemia is a condition that is characterized by the increased levels of a certain immunoglobulin in the blood serum. [1] The name of the disorder refers to an excess of proteins after serum protein electrophoresis (found in the gammaglobulin region). [citation needed]
The cause of this difference was pinpointed in 1956 and 1957, when Vernon Ingram used protein fingerprinting (a combination of electrophoresis and chromatography) to show that the key difference between normal hemoglobins and sickle cell hemoglobins was a single difference in one chain of the protein: a glutamic acid residue on the normal ...
Those who are heterozygous for the sickle cell allele produce both normal and abnormal hemoglobin (the two alleles are codominant with respect to the actual concentration of hemoglobin in the circulating cells). Sickle cell disease is a blood disorder wherein there is a single amino acid substitution in the hemoglobin protein of the red blood ...
