Abstract: Sulfonated 2(7)-aminoacridone and 1-aminopyrene dyes and their use as fluorescent tags, in particular for carbohydrate analysis The invention relates to fluorescent dyes with multiple negatively charged groups in their ionized form which are aminoacridone sulfonamides or 1-aminopyrenes having of one of the following general formulae A-D: Formula (A), Formula (B), Formula (C), Formula (D), wherein the ionizable groups X are typically selected from the following: SH, COOH, SO3H, OSO3H, OP(O)(OH)2, OP(O)(OH)Ra, P(O)(OH)2, P(O)(OH)Ra, where Ra?C1-C4alkyl or substituted C1-C4alkyl. The invention further relates to the use of these dyes as fluorescent tags, in particular for reducing sugars and glycans.

Abstract: The present invention relates to improved (simplified/easier, more robust and more reproducible) methods for identification of carbohydrates compositions, e.g. out of complex carbohydrate mixtures, as well as the determination of carbohydrate mixture composition patterns (e.g.: of glycosylation patterns) based on advanced internal standards to determine precise and highly reproducible migration and retention time indices using novel fluorescent dyes in combination with high performance separation technologies, like capillary (gel) electrophoresis (C(G)E) or (ultra)high performance liquid chromatography (U)HPLC with a highly sensitive detection like (laser induced) fluorescence detection.

Abstract: The invention is directed to a method for detecting a target moiety in a sample of biological specimens by providing a conjugate with the general formula (I) characterized in contacting the sample of biological specimens with at least one conjugate (I), thereby labeling the target moiety recognized by an antigen recognizing moiety with the conjugate (I); exciting the labelled target moieties with light having a wavelength within the absorbance spectrum of the fluorescent moiety FL; detecting the labelled target moieties by detecting the fluorescence radiation emitted by the fluorescent moiety FL and degrading the fluorescent moiety FL of the labelled target moieties by irradiating the conjugate with light having a wavelength within the absorbance spectrum of fluorescent moiety FL for a time sufficient to deliver enough energy to reduce the fluorescence radiation emitted by the fluorescent moiety FL at least by 75% of the initial fluorescence radiation.
