I would like to use my Qubit 4 Fluorometer with the Qubit 1X dsDNA BR Assay, but the assay is not listed as an option on the fluorometer. How can I resolve this?

The Qubit 4 Fluorometer needs to be updated. The Qubit 4 Fluorometer can be updated with the USB that was provided with the Qubit. If you do not have the USB, we recommend using an empty 2.0GB that is FAT32 formatted. If the USB is not recognized, leave USB plugged in for a few minutes before running the update. This should give you the assay you need to run the Qubit Assay.

You can find the updates on the Technical Resources for Qubit Fluorometers page.

Which is the best DNA or RNA quantification instrument?

All of the DNA instruments offered by Thermo Fisher Scientific are of excellent quality. To find the right instrument to quantify DNA or RNA in your lab, explore the detailed comparison of UV-Vis spectrophotometers and fluorometers. Things like sensitivity, throughput and budget may be initial considerations when selecting a DNA quantification instrument. You may also consider whether you need target specificity, sample purity information, RNA quality information, or broad dynamic range.

What is the difference between UV and fluorescence DNA quantification? Which DNA quantification technology should I choose?

UV and fluorescence technologies work differently to quantify DNA. UV quantification relies on the intrinsic absorptivity of DNA and RNA molecules, while fluorescence quantification uses dyes that specifically bind to your molecule of choice. With UV technology, quantification isn't as sensitive, but it has a broader dynamic range and also gives data about sample purity‒plus it is faster because there is no reagent prep. With fluorescence technology you get higher sensitivity and molecule-specific data, but it has lower dynamic range and reagent prep is required. The technology you need will depend on what features are important for your lab and experimentation.
