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 .

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 BUN, or blood urea nitrogen test, measures the amount of urea nitrogen in your blood. Urea nitrogen is a waste product that forms as your body breaks down proteins. It's carried in your blood and then removed by your kidneys when you urinate (pee).

Tests
This test measures the level of C-peptide in a sample of your blood or urine (pee). C-peptide is a chain of amino acids (the building blocks of proteins) that your pancreas makes in the process of making insulin. Insulin is a hormone that your pancreas makes to help blood glucose (blood sugar) get into your cells, where it can be used for energy. This helps keep your blood glucose at healthy levels.

Indicators
Proteins released into blood when heart muscle is injured; the central laboratory marker in suspected heart attack.
Tests
Blood proteins released when heart muscle is injured; the primary laboratory marker in the evaluation of possible acute myocardial infarction.

Tests
This test looks for CCP (cyclic citrullinated peptide) antibodies in your blood. CCP antibodies, also called anti-CCP antibodies, are a type of antibody called autoantibodies. Antibodies and autoantibodies are proteins made by the immune system :

Indicators
A protein complex comprised of one T-cell surface glycoprotein CD3 delta chain (CD3D), one T-cell surface glycoprotein CD3 gamma chain (CD3G) and two T-cell surface glycoprotein CD3 epsilon chains (CD3E). CD3D, CD3G and CD3E are transmembrane proteins with one extracellular immunoglobulin domain and one intracellular ITAM domain. The CD3 complex is a T-cell co-receptor that noncovalently associates with either the disulfide bound heterodimeric alpha/beta T-cell receptor (TCR) or gamma/delta TCR and two copies of the accessory protein, T-cell surface glycoprotein CD3 zeta chain (CD247), which is a transmembrane protein with three ITAM domains. The TCR moiety of the TCR-CD3 complex binds to MHC and processed antigens on antigen presenting cells, which triggers phosphorylation of and cellular propagation of the signal by CD247 and the CD3 complex.
Glossary Term
A structure found in cells that is comprised of a strand of linearized double-stranded DNA plus proteins that package the DNA in a condensed coil form and regulate chromosomal function.

Indicators
Coagulation factor IX (461 aa, ~52 kDa) is encoded by the human F9 gene. This protein plays a role in the intrinsic pathway of blood coagulation through the mediation of proteolysis that converts factor X into an active protease.
