FAQ
What is a good concentration of DNA?
The most common purity calculation is the ratio of the absorbance at 260nm divided by the reading at 280nm. Good-quality DNA will have an A260/A280 ratio of 1.7–2.0.
How do you calculate DNA concentration?
You can calculate the DNA concentration using the formula: concentration [μg/mL] = OD260 * conversion factor.
What is the 260 280 ratio for DNA?
260/280 ratio of ~1.8 is generally accepted as “pure” for DNA; a ratio of ~2.0 is generally accepted as “pure” for RNA.
