| Edman's reagent | C6H5-N==C==S, a reagent that condenses with the free N-terminal amino group of a peptide chain to form a phenylthiohydantoin in the Edman method of identifying N-terminal amino acids. Synonym: Edman's reagent. Acronym: PITC (05 Mar 2000) |
|---|
| Edman reagent | Phenyl isothiocyanate. The classic method for sequence determination of peptides using sequential cleavage of the N terminal residue after reaction with Edman reagent. The N terminal amino acid is removed as a phenylthiohydantoin derivative. (18 Nov 1997) |
|---|---|
| edman degradation | A lab technique used to find out the order of amino acids in a polypeptide (chain of amino acids). It involves using the Edman reagent, phenyl isothiocyanate (PITC), to react one by one with each amino acid, in order. The technique is used in machines which automatically sequence (determine the order of subunits) polypeptides. (09 Oct 1997) |
| Edman method | C6H5-N==C==S, a reagent that condenses with the free N-terminal amino group of a peptide chain to form a phenylthiohydantoin in the Edman method of identifying N-terminal amino acids. Synonym: Edman's reagent. Acronym: PITC (05 Mar 2000) |
| Edman, Pehr | <person> Australian scientist, 1916-1977. See: Edman method, Edman's reagent. (05 Mar 2000) |
| amino acid reagent | A reagent used in the identification and quantification of amino acids. (05 Mar 2000) |
| Benedict-Hopkins-Cole reagent | <chemistry> Magnesium glyoxalate, made from a mixture of oxalic acid and magnesium, used for testing proteins for the presence of tryptophan. (12 Aug 2000) |
| biuret reagent | An alkaline solution of copper sulfate. (05 Mar 2000) |
| Mandelin's reagent | A solution of ammonium vanadate in sulfuric acid, used in colour tests for alkaloids. (05 Mar 2000) |
| reagent | <technique> A histochemical technique based on periodic acid oxidation of a substance containing the 1,2-glycol grouping. It is used for staining carbohydrates as the resulting dialdehyde reacts with Schiff reagent to form a coloured product. The adjacent hydroxyl groups are oxidized to form aldehydes by periodic acid (HIO4) and these aldehyde groups react with Schiff's reagent (basic fuchsin decolourised by sulphurous acid) to give a purple colour. Acronym: PAS (18 Nov 1997) |
| reagent kits, diagnostic | Commercially prepared reagent sets, with accessory devices, containing all of the major components and literature necessary to perform one or more designated diagnostic tests or procedures. They may be for laboratory or personal use. (12 Dec 1998) |
| reagent strips | Narrow pieces of material impregnated or covered with a substance used to produce a chemical reaction. The strips are used in detecting, measuring, producing, etc., other substances. (12 Dec 1998) |
| Marme's reagent | A solution of potassium iodide and cadmium iodide used in testing for alkaloids. (05 Mar 2000) |
| Marquis' reagent | A solution of formaldehyde in sulfuric acid used in colour tests for formaldehyde. (05 Mar 2000) |
| Girard's reagent | The hydrazine of betaine chloride, used to extract ketonic steroids by forming water-soluble hydrazones with them. (05 Mar 2000) |
| Mecke's reagent | A solution of selenous acid in sulfuric acid, used for colour tests of alkaloids. (05 Mar 2000) |
