Indicators
An essential amino acid in juvenile humans, Arginine is a complex amino acid, often found at active site in proteins and enzymes due to its amine-containing side chain. Arginine may prevent or treat heart and circulatory diseases, combat fatigue, and stimulate the immune system. It also boosts production of nitric oxide, relaxing blood vessels, and treating angina and other cardiovascular problems. Arginine is also an important intermediate in the urea cycle and in detoxification of nitrogenous wastes. (NCI04)
Tests
Autoantibody testing checks a sample of your blood for autoantibodies, proteins made by the immune system .
For everyone & professionals
Tests
The determination of the amount of B-cell lymphoma 6 protein in a sample.
For professionals
Indicators
This gene is involved in cellular growth regulation and is purported to have tumor suppression activity.
Indicators
A fusion gene that results from a translocation t(9;22)(q34;q11) that fuses the 5' part of the BCR gene to the 5' side of exon 2 of the ABL1 gene. There are 3 potential products that are formed depending on which BCR exon has the breakpoint. All of the protein products have constitutively active tyrosine kinase activity. This fusion is associated with both chronic myeloid leukemia and acute lymphoblastic leukemia.
Tests
A beta-2 microglobulin tumor marker test measures the amount of a protein called beta-2 microglobulin (B2M) in your body fluids. The test usually uses a sample of your blood. It may also be done using urine (pee) or in rare cases cerebrospinal fluid (CSF).
For everyone & professionals
Tests
The determination of the amount of the 1-42 amino acid beta amyloid protein isoform present in a sample.
For professionals
Tests
The determination of the ratio of beta-1 globulin compared to beta protein present in a sample. The measurement may be expressed as a ratio or percentage.
For professionals
Tests
The determination of the ratio of the beta-1 globulin to albumin in a biological specimen.
For professionals
Indicators
Beta-2-glycoprotein 1 (345 aa, ~38 kDa) is encoded by the human APOH gene. This protein is involved in binding to phospholipids, glycosaminoglycans and other negatively charged substances.
Indicators
Beta-2-microglobulin protein (119 aa, ~14 kDa) is encoded by the human B2M gene. This protein plays a role in immune responses and is a key component of major histocompatibility complex class I molecules. The protein is localized to the surface of cells and is utilized as a prognostic marker in persons with cancers that involve white blood cells. The polypeptide is also used as a marker in kidney damage diagnosis and in the detection of viral infection.
Glossary Term
A storage facility of biospecimens that includes tissue samples, fluids, and molecular derivatives such as DNA, RNA, and proteins. The biorepository has stringent guidelines regarding the standardized collection, handling, storage, and documentation of biological specimens.
