| sulforhodamine B | C27H29N207S2Na;a xanthene dye derivative, a fluorochrome used for tagging proteins by a sulfamido condensation; employed in immuno-fluorescence alone or in combination with fluorescein isothiocyanate for the simultaneous microscopic detection of two antigens in contrasting red and green colours. Synonym: lissamine rhodamine B 200. (05 Mar 2000) |
| sulformethoxine | <chemical> A long acting sulfonamide that is used, usually in combination with other drugs, for respiratory, urinary tract, and malarial infections. Pharmacological action: anti-infective agents, anti-infective agents, urinary, antimalarials. Chemical name: Benzenesulfonamide, 4-amino-N-(5,6-dimethoxy-4-pyrimidinyl)- (12 Dec 1998) |
| sulfosalicylic acid | HOC6H3(CO2H)SO3H; 3-carboxy-4-hydroxybenzenesulfonic acid;used as a test for albumin and ferric ion. Synonym: salicylsulfonic acid. (05 Mar 2000) |
| sulfosalicylic acid turbidity test | A test for measurement of protein in the urine; sulfosalicylic acid precipitates protein in the urine with a turbidity that is approximately proportional to the concentration of protein in a solution. (05 Mar 2000) |
| sulfosol | A hydrosol with sulfuric acid instead of water as the dispersion means. (05 Mar 2000) |
| sulfotransferase | Generic term for enzymes in EC sub-subclass 2.8.2 catalyzing the transfer of a sulfate group from 3'-phosphoadenylyl sulfate (active sulfate) to the hydroxyl group of an acceptor, producing the sulfated derivative and 3'-phosphoadenosine 5'-phosphate. Synonym: sulfikinase, sulfokinase. (05 Mar 2000) |
