The determination of the amount of alpha-2 globulin present in a sample.
Pruebas
The determination of the amount of alpha-2 macroglobulin present in a sample.
Indicadores
Alpha-2-macroglobulin (1474 aa, ~163 kDa) is encoded by the human A2M gene. This protein has activity as a protease inhibitor.
Pruebas
The determination of the number of helper alpha-beta T-lymphocytes in a sample.
Pruebas
The determination of the ratio of a sub-population of alpha-beta T-lymphocytes to total alpha-beta T-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.

Indicadores
The orally bioavailable alpha form of the naturally-occurring fat-soluble vitamin E, with potent antioxidant and cytoprotective activities. Upon administration, alpha-tocopherol neutralizes free radicals, thereby protecting tissues and organs from oxidative damage. Alpha-tocopherol gets incorporated into biological membranes, prevents protein oxidation and inhibits lipid peroxidation, thereby maintaining cell membrane integrity and protecting the cell against damage. In addition, alpha-tocopherol inhibits the activity of protein kinase C (PKC) and PKC-mediated pathways. Alpha-tocopherol also modulates the expression of various genes, plays a key role in neurological function, inhibits platelet aggregation and enhances vasodilation. Compared with other forms of tocopherol, alpha-tocopherol is the most biologically active form and is the form that is preferentially absorbed and retained in the body.
