  • Patent number: 5705649
    Abstract: The present invention provides novel dyes for staining proteins, particularly those in electrophoretic gels, and detecting the proteins with high sensitivity. The dyes of the invention are derivatives of known dyes that are more hydrophobic than the corresponding, known dyes and, in electrophoretic gels, including polyacrylamide gels with sodium dodecyl sulfate, form easily detectable, non-covalent complexes with proteins. In some cases, the corresponding, known dyes bind to protein covalently. The complexes of protein with some dyes of the invention can be detected with high sensitivity simply by observation of the color of the complexes by eye. The complexes of protein with other dyes of the invention are detected by observation of the fluorescence of the complexes. Dyes of the invention include derivatives of Coomassie.RTM. dyes, acid blue 25, dansyl chloride, fluorescein, 2-methyl-2,4-diphenyl-3(2H)-furanone, and (7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino alkanoates.

  • Patent number: 5698535
    Abstract: New inclusion complexes which are stable in their so-lid state formed of SIN-1A and cyclodextrins or cyclodextrin derivatives and optionally also containing ions as catalyst or stabilizer. The complexes release nitric oxide at room temperature upon dissolving in water or aqueous systems. The ions are preferably carboxylic acid anions such as acetate, formiate, propionate, ascorbinate, tartarate and/or lactate and/or inorganic acid anions such as phosphate, phosphite, borate, carbonate, hydrocarbonate, sulfate, sulfite and/or cations such as alkali and/or ammonium.Pharmaceutical compositions as well as kits containing the complexes. The kits are to be used as NO-liberating standards to release NO in a predictable amount and rate on dissolving in aqueous media.
