  • Protein analysis using a polymethine marker dye
    Patent number: 9297807
    Abstract: A kit for optically detecting proteins, in particular lipoproteins, in a sample, the kit comprising: a chip for performing a separation of the proteins, in particular of the lipoproteins, wherein the chip comprises at least one well for receiving the sample, and a separation channel coupled to the at least one well and being adapted for separating different compounds and a marker dye which contains a polymethine of the general formula (I) wherein Z is a substituted derivative of benzooxazole, benzodiazole, 2,3,3-trimethylindolinine, 2,3,3-trimethyl-4,5-benzo-3H-indolinine, 3- and 4-picoline, lipidine, chinadine and 9-methylacridine derivatives with the general formula IIa or IIb or IIc and wherein X is selected from the group consisting of O, S, Si, N-alkyl and C(alkyl)2, n is 0, 1 , 2 or 3, R1 to R14 are independently selected from the group consisting of hydrogen, alkyl, alkoxy, cycloalkyl, linear or branched alkenyl, cycloalkenyl, aryl, heteroaryl, heterocycle, hydroxy, carboxy, amine, alkyl-substituted am
    Type: Grant
