The Nanodrop is one of the most important pieces of equipment in the lab. Here are 8 tips when using the Nanodrop to measure nucleic acids in your sample. Always clean the pedestals before turning the Nanodrop on by pipetting 2 μL of distilled water onto the lower pedestal and closing the upper arm.

To accurately measure the RNA concentrations in your samples you need to use a dye-binding fluorometric assay ( Qubit, picogreen). The Nanodrop is consistently overestimating your sample concentration and you'll want to make sure your input for polyA selection is in the range

Nano-drop was very poorly explained to me, can someone tell me in basic terms what calculation is used to estimate concentration of DNA. I know this is a joke, but does it really? I don't actually use a Nanodrop on a daily basis, how large is the range or what's the issue?

› Get more: Rna concentration uvShow All. Measuring RNA with NanoDrop - Protocol Place. How. Details: A lower than expected concentration of RNA indicates low cell numbers in the sample, poor homogenization of samples, or too much volume of water used in the elution step of RNA

I want to measure the RNA concentration after in vitro transcription reaction. However, I have a lot of DNA template in the sample. Is it possible for me to measure RNA concentration using nanodrop at this step?

10. How should I store purified RNA samples? RNA samples should be stored at -80°C in either Eppendorf LoBind tubes (cat# 022431048) or Axygen 13. Is the NanoDrop a good choice for measuring the concentration of an RNA sample? An A260 measurement on a NanoDrop

RNA quality control using the NanoDrop ND-1000. There are three quality controls that are using the Beer-Lambert law, which predicts a linear change in absorbance with concentration. This depends, however on how you performed the measurement and the source of putative are large making it difficult to measure low concentrations of RNA without losing an unacceptable fraction of
