Quant-iT RiboGreen RNA Reagent is an ultrasensitive fluorescent nucleic acid stain for quantitating RNA in solution. The Quant-iT RiboGreen RNA Assay Kit comes with reagent, dilution buffer, and rRNA standards to provide a linear detection range of 1–200 ng of RNA.

Workflow 

This easy-to-use reagent offers two detection ranges: a high-assay range and a low-assay range for sensitive and broad range detection.  To use, simply prepare the working solution by diluting the provided dye with TE-Buffer, then aliquotting 100 µL of the working solution with standards and samples for a total reaction volume of 200 µL.  RNA is then quantitated using a fluorescence microplate reader (such as Varioskan ALF) at standard fluorescein wavelengths.

Applications

Detecting and quantitating small amounts of RNA is important in many applications including measuring yields of in vitro transcribed RNA and measuring RNA concentrations before performing Northern blot analyses, S1 nuclease assays, RNase protection assays, cDNA library preparation, reverse transcription PCR, and differential display PCR.

Foire aux questions (FAQ)

Why am I getting negative fluorescence values with my Qubit Assays?

Negative fluorescence is a physical impossibility. It is an artifact from software autocorrecting for background signal. This means your reader is picking up and subtracting out background light at the cost of your data. Make sure to do a buffer-only control and assess the type of signal. You may need to switch to a different plate.

What are the linear ranges of the Quant-iT RNA kits?

The linear ranges are:

- Quant-iT RiboGreen RNA Assay: 1 ng/mL to 1 µg/mL
- Quant-iT RNA BR Assay: 20-1,000 ng
- Quant-iT RNA HS Assay: 5-100 ng

What is the difference between the Quant-iT RNA assay and the Quant-iT RiboGreen RNA Assay?

There are several differences:

- The Quant-iT RNA Assay uses a far-red dye (excitation 644 nm/emission 673 nm); the Quant-iT RiboGreen RNA assay uses a green fluorescent dye (excitation 500 nm/emission 525 nm).
- The Quant-iT RNA assay is more specific for RNA.
- Quant-iT RNA Assays are less sensitive than the Quant-iT RiboGreen RNA Assay.

Can I make my own assay for the Qubit Fluorometer?

Yes, you can, for Qubit instruments developed after the original Qubit (1.0) Fluorometer. See MyQubit assay instructions here (http://www.thermofisher.com/us/en/home/life-science/laboratory-instruments/fluorometers/qubit/qubit-assays/myqubit.html.html).

I have a crude lysate. Will the Quant-iT and Qubit assays work?

Generally, the cleaner the sample the better. Some salts, proteins, and detergents are tolerated in the assays; see the specific assay protocol for which ones and at what concentrations.

Abstract
A fluorescence-based assay for multisubunit DNA-dependent RNA polymerases.
Authors:Kuhlman P, Duff HL, Galant A
Journal:Anal Biochem
PubMed ID:14690681
The properties of DNA-dependent RNA polymerases have been studied since the 1960s, but considerable interest in probing RNA polymerase structure/function relationships, the roles of different classes of RNA polymerases in cellular processes, and the feasibility of using RNA polymerases as drug targets still exists. Historically, RNA polymerase activity has been ... More
