The values on Nano-Drop for my RNA extraction were 2.05, 1.66 and 207.4 for 260/280, 260/230 and ng/uL, respectively. Also, the peak of the highest reading was on 260nm. However, when I cleaned the sample from DNA by using TURBO DNase, the results were 1.89, 2.18 and 1858.1 ng/uL, and the peak of the highest reading changed from 260 to 269nm.
