WebFeb 8, 2024 · The actual ratio will depend on the composition of the nucleic acid. The 260/230 values for “pure” nucleic acid are often higher than the respective 260/280 values. Expected 260/230 values are commonly in the range of 2.0-2.2. NEB: In buffered solutions, pure dsDNA has an A260/A280 of 1.85–1.88 and pure RNA has a ratio of around 2.1. Web260nmと280 nmの比率が純度の指標になる。260 nmの吸光度はA260またはOD260と表される。二本鎖DNAは260 nmの吸光度1が約50 μg/mlに相当し,一本鎖DNAおよRNAは260 nmの吸光度1が約33 μg/mlに相当する。この数値を基に核酸の濃度を概することができる。 novant health badge
