WebDNA concentration is estimated by measuring the absorbance at 260nm, adjusting the A 260 measurement for turbidity (measured by absorbance at 320nm), multiplying by the dilution factor, and using the relationship that an A 260 of 1.0 = 50µg/ml pure dsDNA. Concentration (µg/ml) = (A 260 reading – A 320 reading) × dilution factor × 50µg/ml.
