Tests
The determination of the amount of B-cell lymphoma 6 protein in a sample.
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).
Tests
The determination of the amount of the 1-42 amino acid beta amyloid protein isoform present in a sample.
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.
Tests
The determination of the ratio of the beta-1 globulin to albumin in a biological specimen.
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.
Indicators
Hexahydro-2-oxo-1H-thieno(3,4-d)imidazole-4-pentanoic acid. Growth factor present in minute amounts in every living cell. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk. The biotin content of cancerous tissue is higher than that of normal tissue.
Tests
A quantitative measurement for assessing the amount of protein present in a blood sample.
