| affinity | 1. An inherent likeness or relationship. 2. A special attraction for a specific element, organ or structure. 3. <chemistry> The force that binds atoms in molecules, the tendency of substances to combine by chemical reaction. 4. The strength of noncovalent chemical binding between two substances as measured by the dissociation constant of the complex. 5. <immunology> A thermodynamic expression of the strength of interaction between a single antigen binding site and a single antigenic determinant (and thus of the stereochemical compatibility between them), most accurately applied to interactions among simple, uniform antigenic determinants such as haptens. Expressed as the association constant (K litres mole 1), which, owing to the heterogeneity of affinities in a population of antibody molecules of a given specificity, actually represents an average value (mean intrinsic association constant). 6. <chemistry> The reciprocal of the dissociation constant. Origin: L. Affinitas = relationship (06 Oct 1997) |
| affinity adsorbent | <immunology> A support matrix coated with an affinity antibodies. (06 May 1997) |
| affinity antibody | The measure of the interaction between molecules such as a receptor and its ligand. This interaction is reversible. (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) |
| affinity column | <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) |
| affinity labeling | <technique> A method for tagging molecules, such as enzymes, so that they can be more easily detected and studied. The method works by substituting a synthetic substance which is similar to the substance that the enzyme normally bonds with. (09 Feb 1998) |
| affinity labels | Analogs of those substrates or compounds which bind naturally at the active sites of proteins, enzymes, antibodies, steroids, or physiological receptors. These analogs form a stable covalent bond at the binding site, thereby acting as inhibitors of the proteins or steroids. (12 Dec 1998) |
| affinity tag | <biochemistry, molecular biology> A short amino acid sequence, usually engineered onto the N- or C-terminus of a protein, to make its purification easier. (14 Nov 1997) |
| affinous | Pertaining to a marriage in which the partners are related, not by consanguinity, but through another marriage. Origin: L. Affinis, related by marriage, fr. Ad, to + finis, limit (05 Mar 2000) |
| affirmation | 1. Confirmation of anything established; ratification; as, the affirmation of a law. 2. The act of affirming or asserting as true; assertion; opposed to negation or denial. 3. That which is asserted; an assertion; a positive tatement; an averment; as, an affirmation, by the vender, of title to property sold, or of its quality. 4. A solemn declaration made under the penalties of perjury, by persons who conscientiously decline taking an oath, which declaration is in law equivalent to an oath. Origin: L. Affirmatio: cf. F. Affirmation. Source: Websters Dictionary (01 Mar 1998) |
| affirmative | 1. Confirmative; ratifying; as, an act affirmative of common law. 2. That affirms; asserting that the fact is so; declaratory of what exists; answering "yes" to a question; opposed to negative; as, an affirmative answer; an affirmative vote. 3. Positive; dogmatic. "Lysicles was a little by the affirmative air of Crito." (Berkeley) 4. <logic> Expressing the agreement of the two terms of a proposition. 5. <mathematics> Positive; a term applied to quantities which are to be added, and opposed to negative, or such as are to be subtracted. Origin: L. Affirmativus: cf. F. Affirmatif. Source: Websters Dictionary (01 Mar 1998) |
| affix | 1. To subjoin, annex, or add at the close or end; to append to; to fix to any part of; as, to affix a syllable to a word; to affix a seal to an instrument; to affix one's name to a writing. 2. To fix or fasten in any way; to attach physically. "Should they [caterpillars] affix them to the leaves of a plant improper for their food." (Ray) 3. To attach, unite, or connect with; as, names affixed to ideas, or ideas affixed to things; to affix a stigma to a person; to affix ridicule or blame to any one. 4. To fix or fasten figuratively; with on or upon; as, eyes affixed upon the ground. Synonym: To attach, subjoin, connect, annex, unite. Origin: LL. Affixare, L. Affixus, p. P. Of affigere to fasten to; ad + figere to fasten: cf. OE. Affichen, F. Afficher, ultimately fr. L. Affigere. See Fix. Source: Websters Dictionary (01 Mar 1998) |
| afflation | A blowing or breathing on; inspiration. Origin: L. Afflatus, p. P. Of afflare to blow or breathe on; ad + flare to blow. Source: Websters Dictionary (01 Mar 1998) |
| afflatus | 1. A breath or blast of wind. 2. A divine impartation of knowledge; supernatural impulse; inspiration. "A poet writing against his genius will be like a prophet without his afflatus." (Spence) Origin: L, fr. Afflare. See Afflation. Source: Websters Dictionary (01 Mar 1998) |
