Concentration (µg/ml) = (A 260 reading – A 320 reading) × dilution factor × 50µg/ml Total yield is obtained by multiplying the DNA concentration by the final total purified sample volume. DNA yield (µg) = DNA concentration × total sample volume (ml) However, DNA is not the only molecule that can absorb UV light at 260nm.
