Ratios nanodrop
TīmeklisThe high ratios are because I was using 1 uL on the Nanodrop sample pedestal, instead of 2 uL. I've always done this with precious samples in other labs I've worked in with no issues.... but the application scientist said this fixed high 260/230 ratios for him when he was having this problem and it did for me, too.

TīmeklisThe ratio for pure RNA A 260/280 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. TīmeklisNational Center for Biotechnology Information
TīmeklisIn striking contrast, the conversion ratio in nanodrops increases by up to ∼4× with decreasing initial concentration of the reactants. This is an unusual increase in conversion ratio over that expected in bulk solution over this concentration range.
