Web22 de abr. de 2024 · The ratio for pure RNA A260/280 is ~2.0. These ratios are commonly used to assess the amount of protein contamination that is left from the nucleic acid isolation process since proteins absorb at 280 nm.

Web19 de fev. de 2013 · The 260/230 ratio gives you idea about the contaminants in your sample. Guanidine isothiocyanate, which is usually used for RNA isolation, absorbs at 230nm, so that might be what you see. But another explanation might be that your sample is very dilute (how much RNA did you get?), so that your A260 is also very low. Web24 de out. de 2008 · A260/280 does not have to be exactly 2 for a pure sample - the value you have obtained (2.4) indicates that the sample is pretty good.-bitesizebio guy-well RNA 260/280 ratio may be higher than 2. But 2.4 starts to be little to much for me. I would not recommend to use samples with higher ratio than 2.3, although 2.4 may be ok too.-fred_33- Web280 nm are 0.00057 and 0.001 (ng/µL) –1. cm –1. respectively.
