Nucleic Acid Quantification

The quantification of nucleic acids is common to many applications in basic science and clinical research. These assays use either absorbance or fluorescence to measure the concentration of DNA or RNA in samples. Regardless of the method employed, many laboratories have adapted single cuvette protocols to a 96- and 384-well microplate-based format. These standardized formats, with instrumentation capable of recording measurements from them, allow for the rapid quantification of large numbers of samples.

Nucleic acid quantification encompasses key methods including:

  • Spectrophotometric determination of dsDNA, ssDNA, RNA at A260
  • Fluorometric determination of dsDNA with fluorescent dyes, for example, PicoGreen
  • Determination of purity based on A260/A280 ratios
