    When using a path length that is shorter than 10mm, the resultant OD will be reduced by a factor of 10/path length. Using the example above with a 3 mm path length, the OD for the 100 μg/mL sample would be reduced to 0.6. To normalize the concentration to a 10mm equivalent, the following is done: 0.6 OD X (10/3) * 50 μg/mL=100 μg/mL

    en.wikipedia.org/wiki/Qubit_fluorometer

    The Qubit fluorometer method is to use fluorescent dyes to determine the concentration of either nucleic acids or proteins in a sample. Specialized fluorescent dyes bind specifically to the substances of interest. A spectrophotometer is used in this method to measure the natural absorbance of light at 260 nm (for DNA and RNA) or 280 nm (for ...

    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 purified RNA is analysed for quality (by capillary electrophoresis) and quantity (for example, by using a NanoDrop or NanoPhotometer spectrometer). If the material is of acceptable quality and sufficient quantity is present (e.g., >1μg, although the required amount varies by microarray platform), the experiment can proceed.

    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 ...

    [25] [60] Theoretically, there is no upper limit of quantification in RNA-Seq, and background noise is very low for 100 bp reads in non-repetitive regions. [ 10 ] RNA-Seq may be used to identify genes within a genome , or identify which genes are active at a particular point in time, and read counts can be used to accurately model the relative ...

  9. Reverse transcription polymerase chain reaction - Wikipedia

    en.wikipedia.org/wiki/Reverse_transcription...

    Competitive RT-PCR technique is used for absolute quantification. It involves the use of a synthetic “competitor” RNA that can be distinguished from the target RNA by a small difference in size or sequence. It is important for the design of the synthetic RNA be identical in sequence but slightly shorter than the target RNA for accurate results.
