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. WebFeb 1, 2024 · Here, half a milliliter of the 1:100 dilution allowed you to count CFU. 2. Divide the CFU from the dilution (179) by the result from Step 1 (0.005) to yield 35,800 CFU. This means that the original 1 mL of sample that was diluted contains 35,800 CFU. Another way to put this is to say that the original sample has 35,800 CFU/mL. ealing flats https://remingtonschulz.com
