  • Patent number: 8137990
    Abstract: Methods and compound useful for detecting a source of hydrogen peroxide are disclosed wherein a signalling compound of the formula: is reacted with peroxide. Sig is a non-polymeric organic group, B is a boron atom, and each R is independently selected from hydrogen, alkyl and aryl groups and can be joined together as a straight or branched alkylene chain forming a ring or as an aromatic ring. A detectable product compound of the formula Sig-OH or Sig-O?is produced and detected by measuring color, absorbance, fluorescence, chemiluminescence, or bioluminescence. The signalling compound itself does not possess the detectable property or does so only to a very weak degree. The methods can be used as a detectable signal in assays for peroxide or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.
    Type: Grant

  • Patent number: 7390670
    Abstract: Methods and compound useful for detecting a source of hydrogen peroxide are disclosed wherein a signalling compound of the formula: is reacted with peroxide. Sig is a non-polymeric organic group, B is a boron atom, and each R is independently selected from hydrogen, alkyl and aryl groups and can be joined together as a straight or branched alkylene chain forming a ring or as an aromatic ring. A detectable product compound of the formula Sig—OH or Sig—O? is produced and detected by measuring color, absorbance, fluorescence, chemiluminescence, or bioluminescence. The signalling compound itself does not possess the detectable property or does so only to a very weak degree. The methods can be used as a detectable signal in assays for peroxide or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.

  • Patent number: 6919463
    Abstract: Compounds useful for detecting a source of hydrogen peroxide are disclosed wherein a signalling compound of the formula: is reacted with peroxide. Sig is an aromatic or heteroaromatic ring group, B is a boron atom, and R5 and R6 are independently selected from hydrogen and lower alkyl groups and can be joined together as a straight or branched alkylene chain forming a five or six-membered ring. A detectable product compound of the formula Sig-OH Is produced and detected by measuring color, fluorescence, chemiluminescence, or bioluminescence. The signalling compound itself does not possess the detectable property or does so only to a very weak degree. The compounds can be used for detection in assays for peroxide or peroxide-producing enzymes and in assays employing enzyme-labeled specific binding pairs.
