| HAT medium | <cell biology, cell culture> A selective growth medium for animal tissue cells that contains Hypoxanthine, the folate antagonist Aminopterin (or amethopterin) and Thymine. Used for selection of hybrid somatic cell lines, as in the production of monoclonal antibodies. In HAT medium, cells are forced to use these exogenous bases, via the salvage pathways, as their sole source of purines and pyrimidines. Parental cells lacking enzymes such as HGPRT or TK can be eliminated whilst hybrids grow. (18 Nov 1997) |

| Czapek-Dox medium | A culture medium used for the cultivation of fungus species and for identification of Aspergillus and Penicillium species. Synonym: Czapek-Dox medium. (05 Mar 2000) |
| Czapek's medium | <cell culture> An agar medium used to grow fungi and soil bacteria which feed on decaying organic material (called saprobes). The medium contents include sugars, water, and salt. (09 Oct 1997) |
| xenobiotic medium chain fatty acid - coenzyme A ligase | <enzyme> Partial amino acid sequence of enzyme from bovine liver mitochondria given I first source; has high sequence homology to human and rat sa protein Registry number: EC 6.2.1.- Synonym: xl-i ligase, xl-i carboxylic acid - CoA ligase (26 Jun 1999) |
| high osmolar contrast medium | Ionic water-soluble iodinated contrast media. Synonym: high osmolar contrast medium. (05 Mar 2000) |
| selective medium | <cell culture> A medium which allows the growth of certain types of microorganisms in preference to others. For example: an antibiotic-containing medium allows the growth of only those microorganisms which are resistant to this antibiotic. (09 Oct 1997) |
| separating medium | Any coating which serves to prevent one surface from adhering to another, in dentistry, a material usually applied to a cast to facilitate separation from the resin denture base after curing; a coating on impressions to facilitate removal of the cast. (05 Mar 2000) |
| Simmons' citrate medium | A diagnostic medium used in the differentiation of species of Enterobacteriaceae, based on their ability to utilise sodium citrate as the sole source of carbon. (05 Mar 2000) |
| hypoxanthine-aminopterin-thymine medium | A type of agar growth medium (a selective medium) which is used to select for cells that are able to make their nucleic acids out of hypoxanthine and/or thymine. All cells are prevented from making nucleotides by any other means (due to the presence of aminopterin or other drugs in the medium), so cells which are unable to use hypoxanthine and/or thymine to do this will not grow, multiply, and become visible colonies. This leaves the cells which are being selected for. (09 Oct 1997) |
| stratum griseum medium | See: gray layer of superior colliculus. (05 Mar 2000) |
| nutrient medium | A substance, either solid or liquid, used for the cultivation, isolation, identification, or storage of microorganisms. Synonym: growth medium, medium, nutrient medium. (05 Mar 2000) |
| support medium | The material in which separation takes place, as in separation of components in electrophoresis. (05 Mar 2000) |
| defined medium | <cell culture> Cell culture medium in which all components are known. In practice this means that the serum (that is normally added to culture medium for animal cells) is replaced by insulin, transferrin and possibly specific growth factors such as platelet-derived growth factor. (18 Nov 1997) |
| differential medium | A medium which is used to differentiate different types of microorganisms based on their different colours or colony shapes. Examples of differential media are: Macconkey's agar and SS agar. (09 Oct 1997) |
| dispersion medium | The medium or fluid in which a disperse is suspended. Synonym: continuous phase, dispersion medium, dispersion phase, external medium. (05 Mar 2000) |
