The immunoglobulins or antibodies are generally the only proteins present in the normal gamma region. Of note, any protein migrating in the gamma region will be stained and appear on the gel, which may include protein contaminants, artifacts, or certain medications. Depending on whether an agarose or capillary method is used, interferences vary.
Once set, light chain class remains fixed for the life of the B lymphocyte. In a healthy individual, the total kappa-to-lambda ratio is roughly 2:1 in serum (measuring intact whole antibodies) or 1:1.5 if measuring free light chains, with a highly divergent ratio indicative of neoplasm. The free light chain ratio ranges from 0.26 to 1.65. [1]
X-chromosome. Most antibodies are gamma globulins. Antibodies are made mainly by plasma cells, which are daughter cells of the B cell line.The Btk enzyme plays an essential role in the maturation of B cells in the bone marrow, and when mutated, immature pro-B lymphocytes are unable to develop into pre-B lymphocytes, which normally develop into mature (naive) B cells that leave the bone marrow ...
Free light chains (FLCs) are immunoglobulin light chains that are found in the serum (blood) in an unbound (free) state. In recent decades, measuring the amount of free light chains (FLCs) in the blood has become a practical clinical test. FLC tests can be used to diagnose and monitor diseases like multiple myeloma and amyloidosis.
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 ...
Dysgammaglobulinemia is a type of immune disorder characterized by a reduction in some types of gamma globulins, resulting in heightened susceptibility to some infectious diseases where primary immunity is antibody based. [1] It is distinguished from hypogammaglobulinemia, which is a reduction in all types of gamma globulins. [2]
The human β-globin locus is composed of five genes located on a short region of chromosome 11, responsible for the creation of the beta parts (roughly half) of the oxygen transport protein Haemoglobin. This locus contains not only the beta globin gene but also delta, gamma-A, gamma-G, and epsilon globin.
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).
