| ionic strength | Symbolised as g/2 or I and set equal to 0.5σmizi2, where mi equals the molar concentration and zi the charge of each ion present in solution; if molar concentrations (ci) are used instead of molality (and the solution is dilute), then I == 0.5(1/ρo)σcizi2 where ρo is the density of the solvent; a number of biochemically important events (e.g., protein solubility and rates of enzyme action) vary with the ionic strength of a solution.

| tensile strength | The maximum stress a material subjected to a stretching load can withstand without tearing. (12 Dec 1998) |
| yield strength | The amount of stress at which a permanent (plastic) deformation in a component becomes measurable (usually taken as 0.2% permanent strain). (05 Mar 2000) |
| ultimate strength | The maximum stress achieved prior to failure of a component on a single application of the load. (05 Mar 2000) |
| fatigue strength | The stress level below which a particular component will survive an indefinite number of load cycles (typically about 50% of the ultimate strength of the component). (05 Mar 2000) |
| agar-gel reaction | <immunology> The reaction between an antibody and an antigen during an immunology lab procedure where the two are allowed to diffuse toward each other through an agar-gel medium. Lines of precipitation form in the places on the gel where the two react with each other and shows where the reaction has occurred. (09 Oct 1997) |
| agarose gel electrophoresis | <procedure> A type of electrophoresis that uses a matrix of highly purified agar to separate large nucleotides in size. (06 May 1997) |
| aluminum hydroxide gel | A suspension containing Al2O3, mainly in the form of aluminum hydroxide, used as an antacid; a dried form, with the same use, is obtained by drying the product of interaction in aqueous solution of an aluminum salt with ammonium or sodium carbonate. (05 Mar 2000) |
| aluminum phosphate gel | An aqueous suspension of between 4.0 and 5.0% of aluminum phosphate; used as an antacid. (05 Mar 2000) |
| bag-gel implant | An implant composed of a silicone rubber bag containing a silicone gel; used in augmentation mammaplasty. (05 Mar 2000) |
| gel | Jelly like material formed by the coagulation of a colloidal liquid. Many gels have a fibrous matrix and fluid filled interstices: gels are viscoelastic rather than simply viscous and can resist some mechanical stress without deformation. Examples are the gels formed by large molecules such as collagen (and gelatin), agarose, acrylamide and starch. (18 Nov 1997) |
| gel diffusion | Diffusion in a gel, as in the case of gel diffusion precipitin tests in which the immune reactants diffuse in agar. See: immunodiffusion. (05 Mar 2000) |
| gel diffusion precipitin tests | Precipitin test's in which the immune precipitate forms in a gel medium (usually agar) into which one or both reactants have diffused; generally classified in two types, in one dimension, and in two dimensions. Synonym: gel diffusion reactions. (05 Mar 2000) |
| gel diffusion precipitin tests in one dimension | Precipitin test's in which antigen solution and antibody incorporated in agar are layered in tubes, permitting effective diffusion in the vertical dimension; the antibody-containing agar may be overlaid directly with antigen solution (single (gel) diffusion in one dimension).
