Integrity 260
NettetFor DNA, ε = 50 μg/mL. An OD at 260 nm (A 260) reading of 1.0 is equivalent to approximately 40 μg/mL of pure RNA and 50 μg/mL of pure double-stranded DNA. However, the Beer-Lambert law is only valid for OD readings up to 2 and the stated OD/concentration relationship relies upon the samples being pure. Nettet4. feb. 2024 · By monitoring absorbance at 280 and 260 nm, each elution peak corresponding to different capsid species was characterized for its protein and DNA content based on its A260/A280 ratio.
