260/280 and 260/230 Ratios - GGBC

TīmeklisLa relación de absorbancia a 260 y 280 nm se utiliza para evaluar la pureza del ADN. Una proporción de ∼1,8 generalmente se acepta como "pura" para el ADN. Si la relación es considerablemente más baja (≤1,6), puede indicar la presencia de proteínas, fenol u otros contaminantes que se absorben fuertemente a 280 nm o cerca de ellos. TīmeklisSimilarly, absorbance at 230 nm is accepted as being the result of other contamination; therefore the ratio of A 260 / A 230 is frequently also calculated. 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. ウィンディ攻略アルセウス
