How to determine the concentration and purity of a DNA

May 12, 2017 The ratio of absorbance at 260 and 280nm is used to assess the purity of DNA and RNA. A ratio of ~1.8 is generally accepted as “pure” for DNA; a ratio of ~2.0 is generally accepted as “pure” for RNA. If the ratio is appreciably lower in either case, it may indicate the presence of protein, phenol or other contaminants that absorb strongly at or near 280nm. The following table indicates a general …
