    Reliable measurement of DNA concentration and purity is important for many applications in molecular biology where accurate determination of DNA concentration is critical. Impurities in DNA may lead to inaccurate measurement of DNA concentration and could potentially inhibit subsequent labelling reactions. DNA purification helps extract genomic and/or plasmid DNA in the sample quantities that your research requires. Purifying your DNA samples from contaminants also extends their shelf-life and reduces the probability of error when it comes to research results.The ratio of absorbance at 260 and 280 nm is used to assess DNA purity. A ratio of ∼1.8 is generally accepted as “pure” for DNA. If the ratio is appreciably lower (≤1.6), it may indicate the presence of proteins, phenol, or other contaminants that absorb strongly at or near 280 nm.
