| 영문 | fixative | 한글 | 고정액, 고정제 |
|---|---|---|---|
| 설명 | 생물체 또는 그 일부를 고정하기 위한 시약. 조직이나 세포를 가능하면 살아 있을 때와 가까운 상태로 고정하기 위해서 고안한 것으로, 연구의 목적에 따라 무기산-무기염류-염화물-유기산, 그 밖에 여러 종류의 시약이 단독 또는 혼합액으로 사용된다. 약 200여 종이 고안되어 있다. 포르말린은 단백질의 응고작용과 중합작용을 가지고 있기 때문에 우수한 고정액 또는 그 재료가 된다. 그러나 응고작용은 강하나 투과성이 약하므로 이것에 아세트산을 혼합하면 더 우수한 고정액이 된다. |

| methanol | A toxic, colourless, flammable alcohol which is used in some antifreeze and to manufacture formaldehyde. It can cause blindness and other nervous system damage if ingested (09 Oct 1997) |
|---|---|
| methanol-2-mercaptoethanesulfonic acid methyltransferase | <enzyme> Catalyses first reaction in conversion of methanol to methane by methanosarcina barkeri; 24-kD subunit mtac and 49-kD subunit mtab of mt1 corrinoid protein have been sequenced; genbank y08310 Registry number: EC 2.1.1.- Synonym: methanol-coenzyme m methyltransferase, methanol-com methyltransferase, corrinoid protein mt1, mtab gene product, mtac gene product (26 Jun 1999) |
| methanol oxidase | <enzyme> Contains fad and flavin semiquinone; from the yeast hansenula polymorpha Registry number: EC 1.1.99.- (26 Jun 1999) |
| methanol poisoning | Poisoning by ingestion of methanol or wood alcohol. This ingestion leads to a severe metabolic acidosis and can also cause blindness. Liver and kidney damage can result. (27 Sep 1997) |
| acetone fixative | Acetone used at low temperatures to fix enzymes, particularly phosphatases; it removes fat and glycogen. (05 Mar 2000) |
| Altmann's fixative | A bichromate-osmic acid fixative. (05 Mar 2000) |
| Bouin's fixative | A solution of glacial acetic acid, formalin, and picric acid, useful for soft and delicate tissues (as those of embryos) and small pieces of tissues; it preserves glycogen and nuclei and permits brilliant staining, but penetrates slowly, distorts kidney tissue and mitochondria, and does not permit Feulgen stain for DNA. (05 Mar 2000) |
| Carnoy's fixative | Ethanol, chloroform, and acetic acid (6:3:1) or ethanol and acetic acid (3:1), an extremely rapid fixative used for glycogen preservation and as a nuclear fixative. (05 Mar 2000) |
| Marchi's fixative | A mixture of Muller's fixative with osmium tetroxide, with potassium chlorate substituted for the potassium dichromate of Muller's fixative for better results; used to demonstrate degenerating myelin. See: Marchi's stain. (05 Mar 2000) |
| Park-Williams fixative | A fixative for spirochetes, comprised of a 2% solution of osmic acid to the fumes of which the bacteria are exposed for a few seconds. (05 Mar 2000) |
| Regaud's fixative | A fixative containing formaldehyde and sodium dichromate, used to preserve mitochondria but not fat; requires afterchroming and extensive washing. (05 Mar 2000) |
| glutaraldehyde fixative | A fixative used in phosphate or cacodylate buffer for electron microscopy, and as a chromatin and enzyme fixative; may be used preceding osmic acid as a second fixative to add membrane preservation for electron microscopy. (05 Mar 2000) |
| Golgi's osmiobichromate fixative | <chemical> An osmic-bichromate mixture used to demonstrate nerve cells and their processes. (05 Mar 2000) |
| Champy's fixative | A mixture of potassium bichromate, chromic acid, and osmic acid, considered an excellent cytologic fixative with advantages and disadvantages similar to those of Flemming's fixative; it differs from Flemming's fixative in substituting bichromate for acetic acid. (05 Mar 2000) |
| picroformol fixative | A fixative containing formalin and picric acid. (05 Mar 2000) |
