An IQ score is given, ranging from 1 to 10, with larger values indicating a higher quality RNA. Recently, the latest Qubit devices (Qubit 4) can determine RNA quality, similar to that given on a 2100 Agilent Bioanalyzer.
Thus, if you have samples with DNA and RNA in, it is best to use the Qubit to determine the concentration. The necessary reagents enable specific binding to the nucleic acid of interest, meaning concentrations are not affected by the presence of other contaminants. So, if you worry your samples have very low concentrations, it is best to use the Qubit.Īnother advantage the Qubit has over the Nanodrop is its specificity. The sensitivity of the Qubit can be as low as 10 pg/mL, which is far superior to the Nanodrop. The main attraction for using a Qubit is when you have samples with very low concentrations of nucleic acids. All measurements are tube-based, so no cleaning required! However, prior preparation with compatible reagents is required, meaning each sample read will come at a small cost. Simply plug it in and you’re ready to read. The touchscreen device is very basic and can work without a computer. Mastering qPCRĪdditional information on the use of the Nanodrop and Qubit can be found in our Mastering qPCR course. In this article, I will compare the two platforms in terms of nucleic acid analysis (not protein) so you can judge which is the better option to suit your needs. Both work slightly differently and have their own perks. doi:10.1039/c305921a.When it comes to quantifying nucleic acids, there are two preferred main platforms: the Qubit and the Nanodrop.
