The Agilent 2200 TapeStation and the Invitrogen Qubit provide solutions to quantitate and qualify nucleic acid samples. These services are used to screen both RNA and DNA prior to library preparation performed at the High-Throughput Genomics Shared Resource and the assays are included in the cost associated with library preparation. Researchers may also order these services as stand-alone assays. Product descriptions, frequently Asked Questions and Pricing relevant to these assays are provided below.
Frequently Asked Questions
Agilent RNA ScreenTape Assay
How does an Agilent ScreenTape assay work?
Agilent ScreenTapes contain a gel matrix to resolve nucleic acid samples according to molecular weight by electrophoresis.
What is a RIN (RNA Integrity Number)?
The RNA ScreenTape provides a numeric assessment of the integrity of an RNA sample that is reported on a scale between 1 and 10 as a RIN (RNA Integrity Number). The RIN value is therefore used to characterize the quality of the RNA sample and enable direct comparison between different samples. An application note prepared by Agilent that describes the RNA Integrity Number can be reviewed at the following web page: https://www.agilent.com/cs/library/applications/5989-1165EN.pdf
What is the volume and concentration of RNA required for an RNA ScreenTape Assay?
Please provide a volume of 3 ul of purified RNA in water at a concentration of 25-500 ng/ul for samples to be run on an RNA ScreenTape.
Can RNA ScreenTape Assays tolerate contaminants in the RNA Sample?
We recommend purifying RNA with spin-column based purification kits (Qiagen, Zymo Research etc.) that elute RNA with water. However, the High Sensitivity RNA ScreenTape Assay can tolerate solutions with 10 mM Tris and 1 mM EDTA of 50 mM NaCl.
How do I obtain data from a TapeStation assay?
TapeStation data can be obtained by browsing to the Experiment Folder in GNomEx. Click on the “Files” tab and open the “Sample QC” folder and select the files that you would like to download.

Can D1000 ScreenTape Assays tolerate contaminants in the sample?
We recommend purifying DNA with spin-column based purification kits (Qiagen, Zymo Research etc.) that elute the DNA in 10 mM Tris pH 8.5. However, A D1000 ScreenTape can tolerate 20 mM KCl, 60 mM Phosphate Buffer, or 240 mM NaCl. The DNA may exhibit an anomalous size distribution if the sample is not purified and provided in an enzyme reaction buffer (pcr reaction, restriction enzyme reaction, etc.).
Can Single-Stranded DNA be accurately resolved on a D1000 ScreenTape?
Single-stranded DNA tends to run with a lower mobility (higher apparent MW) than expected when resolved on a D1000 ScreenTape. Over-amplification of sequencing libraries may result in a substantial fraction of single-stranded DNA may exhibit two distinct peaks- -one of the appropriate size distribution that represents double-stranded DNA and a second peak that represents single-stranded DNA that is inaccurately resolved at an apparent higher molecular weight.

Invitrogen Qubit dsDNA HS Assay
What is the volume and concentration of DNA required for a Qubit dsDNA HS Assay?
Please provide a volume of 3 ul of purified DNA at a concentration of 0.05 to 100 ng/ul for the Qubit dsDNA High Sensitivity Assay.
Is the Qubit dsDNA HS Assay more accurate than a NanoDrop reading for the measurement of DNA concentration?
A NanoDrop spectrophotometer is unable to distinguish between DNA, RNA, oligonucleotides, free nucleotides and other nucleic acid species. An A260 measurement on a NanoDrop represents any form of nucleotide. In contrast to a NanoDrop reading, the Qubit dsDNA High Sensitivity Assay uses a dye that is highly selective for binding double-stranded DNA and therefore is able to accurately determine DNA concentrations in the presence of RNA or other nucleic acid species which can comprise a substantial fraction of many samples.
Can I purchase Qubit reagents and tubes to measure my samples on a Qubit instrument at the High-Throughput Genomic Shared Resource?
A version 2 Qubit instrument is available in the entryway of the High-Throughput Genomics Shared Resource that can be used by researchers that have purchased their own Qubit reagents and Qubit tubes.
