At a wavelength of 260 nm, the average extinction coefficient for double-stranded DNA is 0.020 (μg/mL) −1 cm −1, for single-stranded DNA it is 0.027 (μg/mL) −1 cm −1, for single-stranded RNA it is 0.025 (μg/mL) −1 cm −1 and for short single-stranded oligonucleotides it is dependent on the length and base composition.
Upon binding to DNA, the dye molecules assume a more rigid shape and increase in fluorescence by several orders of magnitude, most likely due to intercalation between the bases. [ 9 ] [ 10 ] The Qubit fluorometer, a device designed to measure fluorescence signals from samples, operates by correlating these signals with known concentrations of ...

Gene expression and RNA quantification studies have benefited from the increased precision and absolute quantification of dPCR. [91] RNA quantification can be accomplished via RT-PCR, wherein RNA is reverse-transcribed into cDNA in the partitioned reaction itself, and the number of RNA molecules originating from each transcript (or allelic ...
The quantification is expressed as the change in expression levels of mRNA interpreted as complementary DNA (cDNA, generated by reverse transcription of mRNA). Relative quantification is easier to carry out as it does not require a calibration curve as the amount of the studied gene is compared to the amount of a control reference gene.
RNA-Skim RNA-Skim: a rapid method for RNA-Seq quantification at transcript-level. rSeq rSeq is a set of tools for RNA-Seq data analysis. It consists of programs that deal with many aspects of RNA-Seq data analysis, such as read quality assessment, reference sequence generation, sequence mapping, gene and isoform expressions (RPKMs) estimation, etc.
The assay is using S1 nuclease, which degrades single-stranded DNA and RNA into oligo- or mononucleotides, leaving intact double-stranded DNA and RNA. In the nuclease hybridization assay, the oligonucleotide analyte is captured onto the solid support such as a 96-well plate via a fully complementary cutting probe.
The other major high throughput technique employed in the quantification of specific RNA molecules is quantitative PCR, after reverse transcription of the RNA to cDNA. Several different short single-stranded DNA molecules (oligonucleotides) are used in a branched DNA-assay. The capture and capture-extender oligonucleotide bind to the target ...
