statistical analysis
| immunoglobulin inv allotypes | Hereditary allotypic markers associated with the light chain of IgG. (12 Dec 1998) |
|---|---|
| immunoglobulin isotypes | The classes of immunoglobulins found in any species of animal. In man there are nine classes that migrate in five different groups in electrophoresis; they each consist of two light and two heavy protein chains, and each group has distinguishing structural and functional properties. (12 Dec 1998) |
| immunoglobulin joining region | Segment of light and heavy chains of mouse and human immunoglobulins where the genes for the variable region upstream join those of the constant region downstream (an important part of the antibody diversity mechanism). In the joining region of the light chain are the genes coding for amino acids 96 to 107. (12 Dec 1998) |
| immunoglobulin M | <immunology> An immunoglobulin M molecule (970 kD) is built up from five immunoglobulin G type monomers joined together, with the assistance of J chains, to form a cyclic pentamer. Immunoglobulin M binds complement and a single molecule bound to a cell surface can lyse that cell. Immunoglobulin M is usually produced first in an immune response before immunoglobulin G. The human red cell isoantibodies are immunoglobulin M antibodies. Heavy chain (mu chain) is rather larger than the heavy chains of other immunoglobulins. (30 Mar 1998) |
| immunoglobulin superfamily | <immunology> A large group of proteins with immunoglobulin like domains. most are involved with cell surface recognition events. Sequence homologyy suggests that immunoglobulins, MHC molecules, some cell adhesion molecules and cytokines receptors share close homology and thus belong to a multigene family. (30 Mar 1998) |
| immunoglobulin switch region | Site on a segment of a B-cell immunoglobulin heavy-chain gene where recombination or rearrangement can occur, expressed as isotype or allotype switching, maturation of immune response, or recombination of DNA molecules. It is found on genes encoding all five immunoglobulin heavy chains. (12 Dec 1998) |
| immunoglobulin variable region | That region of the immunoglobulin (antibody) molecule that varies in its amino acid sequence and composition, confers the antigenic specificity, and is thought to comprise the binding site for the antigen. It is located at the n-terminus of the fab fragment of the immunoglobulin. It includes hypervariable and framework regions, vh family subgroups, and the complementarity-determining region. (12 Dec 1998) |
| intravenous immunoglobulin | <pharmacology> A sterile solution of concentrated antibodies extracted from healthy people. IVIG is used to prevent bacterial infections in people with low or inappropriate antibody production. Injected into a vein or muscle. (09 Oct 1997) |
| tetanus immunoglobulin | <protein> A protein antibody to tetanus toxin, given as passive immunity for those lacking any prior tetanus vaccination. (27 Sep 1997) |
| thyroid stimulating immunoglobulin | <protein> A test that measures the amount of an antibody (thyroid stimulating antibody) which is directed against a receptor for TSH on the thyroid gland. This antibody acts like TSH and stimulates the thyroid to produce excessive amounts of thyroid hormone. The presence of this antibody generally indicates Grave's disease (hyperthyroidism). (27 Sep 1997) |
| accumulation analysis | A technique in which an intermediate of a metabolic pathway accumulates due to selective inhibition of a particular step in that pathway or in a mutant that is deficient in a certain step. The intermediate is then isolated, analyzed, and identified. (05 Mar 2000) |
| activation analysis | <radiobiology> Method for identifying and measuring chemical elements in a sample of material. Sample is first made radioactive by bombardment with neutrons, charged particles, or gamma rays. Newly formed radioactive atoms in the sample then give off characteristic radiations (such as gamma rays) that tell what kinds of atoms are present, and how many. (09 Oct 1997) |
| actuarial analysis | The application of probability and statistical methods to calculate the risk of occurrence of any event, such as onset of illness, recurrent disease, hospitalization, disability, or death. It may include calculation of the anticipated money costs of such events and of the premiums necessary to provide for payment of such costs. (12 Dec 1998) |
| amino acid analysis | Determination and identification of amino acid content of a macromolecule, identification of a specific amino acid in macromolecules, often a mutated protein, identification and quantitation of amino acid content in blood plasma or urine; a key diagnostic aid. (05 Mar 2000) |
| analysis | <technique> The separation into component parts or elements, the act of determining the component parts of a substance. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
