- Quenching dye for labeling biomolecules and method for preparing the same
-
The present disclosure provides a quenching dye with an anthraquinone structure, which has a broad and high absorption spectrum in the visible and near-infrared wavelength regions and exhibits high stability and superior solubility in aqueous conditions. A quenching dye composition containing the anthraquinone compound according to the present disclosure as an active ingredient can be widely used in the field of optical molecular imaging to observe the movement of a biomolecule because it can easily label a biomolecule manipulated in an aqueous buffer.

- Organic dye compound having both pyridiniotriazinyl and vinylsulfone type fiber-reactive groups
-
A compound of the formula, STR1 wherein D is an organic dye moiety, R1 and R2 are independently hydrogen or a substituted or unsubstituted lower alkyl group, R3 is hydrogen or a substituted or unsubstituted lower alkyl, phenyl or naphthyl group, X1 and X2 are independently hydrogen, halogen or a lower alkyl, cyano, carbamoyl, vinyl, β-hydroxyethyl, β-sulfoethyl, β-sulfatoethyl, carboxyl, carboxylic acid ester or sulfonic acid group, and Z is appended to the above-defined D or R3 and stands for --SO2 CH=CH2 or --SO2 CH2 CH2 Y, in which Y is a group capable of being split by the action of an alkali, which is useful for dyeing hydroxyl or amido group-containing fiber materials with excellent build-up properties, thereby giving dyed products having excellent various fastness properties.
