  • Publication number: 20110262918
    Abstract: The present invention is related to a method for the quantification of one or more target ribonucleic acids in a sample comprising the steps of, (i) providing a sample comprising said one or more target ribonucleic acids, (ii) contacting said sample with a ribonucleic acid specific fluorescence dye under conditions allowing for binding of said dye to the one or more ribonucleic acids in said sample, (iii) measuring fluorescence of said RNA-bound dye in said sample, (iv) correlating said measured fluorescence to the total amount of RNA in the sample, (v) reverse transcribing said one or more ribonucleic acids, thereby creating double-stranded nucleic acids, (vi) amplifying said one or more created double-stranded nucleic acids, wherein one or more fluorescence probes specific for said one or more amplification products are present during and/or after amplification under conditions allowing for binding of said one or more probes to said one or more created double-stranded deoxyribonucleic acids in the sample, (
