| gel exclusion chromatography | <investigation> A lab technique, a type of column chromatography, used to separate the components of a mixture by molecular size and to collect the molecules which are larger than a certain size. It is similar to gel filtration, small molecules are slowed or trapped by the pores in the gel beads filling the column, while large molecules, too large to fit into the pores, slide past the beads and get to the bottom of the column first. at this point, the large molecules are collected. Gel exclusion refers to the maximum size of molecule which will fit into the gel bead pores, and this lab technique is used to collect the molecules in the mixture which are larger than, or excluded from, the pores.

| allelic exclusion | <cell biology, genetics> The process whereby one or more loci on one of the chromosome sets in a diploid cell is inactivated (or destroyed) so that the locus or loci is (are) not expressed in that cell or a clone founded by it. For example in mammals one of the X chromosome pairs of females is inactivated early in development (see Lyon hypothesis) so that individual cells express only one allelic form of the product of that locus. Since the choice of chromosome to be inactivated is random, different cells express one or other of the X chromosome products resulting in mosaicism. The process is also known to occur in immunoglobulin genes so that a clone expresses only one of the two possible allelic forms of immunoglobulin. (19 Dec 1998) |
| Pauli's exclusion principle | The theory limiting the number of electrons in the orbit or shell of an atom; that it is not possible for any two electrons to have all four quantum numbers identical. (05 Mar 2000) |
| Devine exclusion | Exclusion of the lower part of the stomach, followed by gastrojejunostomy, for treatment of duodenal ulcer. (05 Mar 2000) |
| diagnosis by exclusion | A diagnosis made by excluding those diseases to which only some of the patient's symptoms might belong, leaving one disease as the most likely diagnosis, although no definitive tests or findings establish that diagnosis. (05 Mar 2000) |
| dye exclusion test | A test to determine cell viability in which a dilute solution of certain dyes (e.g., trypan blue, eosin Y, nigrosin, Alcian blue) is mixed with a suspension of live cells; cells that exclude dye are considered to be alive while cells that stain are considered dead; it is not always an accurate test because it indicates only the structural integrity of the cell membrane.

| exclusion | 1. The act of excluding, or of shutting out, whether by thrusting out or by preventing admission; a debarring; rejection; prohibition; the state of being excluded. "His sad exclusion from the doors of bliss." (Milton) "The exclusion of the duke from the crown of England and Ireland." (Hume) 2. <physiology> The act of expelling or ejecting a foetus or an egg from the womb. 3. Thing emitted. Origin: L. Exclusio: cf. F. Exclusion. See Exclude.

| exclusion of pupil | The condition resulting from posterior annular synechia, in which the iris is bound down throughout the entire pupillary margin, but the pupil is not occluded. Synonym: exclusion of pupil. (05 Mar 2000) |
| absorption chromatography | <investigation> Techniques for separating molecules based on differential absorption and elution. Term for separation methods involving flow of a fluid carrier over a nonmobile absorbing phase. (18 Nov 1997) |
| adsorption chromatography | Chromatography in which separation of substances is achieved by the difference in degree of adsorption of the compounds to a stationary phase. (05 Mar 2000) |
| affinity chromatography | <investigation> A technique of analytical chemistry used to separate and purify a biological molecule from a mixture, based on the attraction of the molecule of interest to a particular ligand which has been previously attached to a solid, inert substance. The mixture is passed through a column containing the ligand attached to the stationary substance, so that the molecule of interest stays within the column while the rest of the mixture continues through to the end. Then, a different chemical is flushed through the column to detach the molecule from the ligand and bring it out separately from the rest of the mixture. (09 Feb 1998) |
| gas chromatography | <technique> A chromatographic technique (a type of column chromatography) in which the stationary phase is solid while the mobile phase is gaseous samples. The gaseous samples are separated based on their different adsorption ability to the solid phase. (09 Oct 1997) |
| gas-liquid chromatography | <technique> A chemistry lab technique, a type of column chromatography, used to separate the components of a mixed substance. The substance is held stationary by an inert solid coated with an inert liquid which is not likely to evaporate (i.e. Is nonvolatile), while a gas (called an eluant) flows past it bringing out the components one at a time. (09 Oct 1997) |
| paper chromatography | <technique> Separation method in which filter paper is used as the support. A type of chromatography in which the stationary phase is a sheet of special-grade filter paper. It is in all other aspects similar to thin-layer chromatography. Not a very sensitive method, but historically important as one of the first methods available for separating natural compounds.
