WebHigh 260/280 and 260/230 ratios suggest that there is a strong absorption of light at 260nm, which is nucleic acid and there is minimal absorption occurring at 280nm and 230nm, which are protein and organic compound, respectively. WebA high 260/230 ratio (above 2.0) indicates that there are very few of these contaminants present within the DNA sample. With 260/230 ratios < 1.5, there are a large number of contaminants present within the sample which can negatively affect many kinds of enzymatic reactions in the NGS workflow. Yield
