What is DNA Quantification and Analysis Techniques about?

A spectrophotometer can be used to determine DNA quantity and quality by measuring absorbance at 260nm, which is proportional to DNA concentration. The ratio of absorbance at 260nm and 280nm determines purity, with a pure sample having a ratio of 1.85-1.88. Samples with low concentration may have interference, so more sensitive fluorescence methods are recommended for impure or low concentration samples.
