Quantify as little as 1 ng of RNA with the Quant-iT RiboGreen RNA Assay Kit or the RediPlate 96 RiboGreen RNA Quantitation Kit. These RNA quantification kits contain Quant-iT RiboGreen RNA reagent, which is one of the most sensitive detection dyes for the quantitation of RNA in solution, with linear fluorescence detection in the range of 1–200 ng of RNA.
Quant-iT RiboGreen RNA Assay Kit
Containing one of the most sensitive detection dyes for the quantitation of RNA, the Quant-iT RiboGreen RNA Assay Kit and the RediPlate 96 RiboGreen RNA Quantitation Kit offer linear fluorescence detection in the range of 1–200 ng of RNA. Both assay kits contain Quant-iT RiboGreen RNA reagent as well as buffers and RNA standards.

RediPlate 96 RiboGreen RNA Quantitation Kit
The RediPlate 96 RiboGreen RNA Quantitation Kit is a rapid, simple, and highly sensitive fluorescence-based RNA-quantitation assay. The microplate is pre-loaded with RiboGreen reagent, which shows bright green fluorescence upon binding to RNA or DNA. Just add buffer and samples to the microplate wells, wait 10 minutes, and read the fluorescence in any standard fluorescence-based microplate reader. The versatile RediPlate 96 design is ideal for either high-throughput RNA quantitation or the measurement of a small sample numbers.

The RediPlate 96 RiboGreen RNA Quantitation Kit also offers the following benefits:
Automatable—a 10 minute incubation time with no separation steps makes the assay ideal for automated, high-throughput measurements
Precise—the average coefficient of variation for replicate assays is ≤5% using a robotic liquid handling system
Convenient—each plate includes pre-measured RNA standards and is ready for immediate use
Easy to read—the assay can be performed using standard fluorescence-based microplate readers

Applications
The RediPlate 96 RiboGreen RNA Quantitation Kit is ideal for measuring yields of RNA preparations for microarray experiments, reverse transcription PCR (RT-PCR), differential display PCR, northern blot analysis, S1 nuclease assays, RNase protection assays, and cDNA library preparations.

Quant-iT RiboGreen RNA Reagent
The Quant-iT RiboGreen RNA Reagent is one of the most sensitive fluorescent dyes for the quantitation of RNA in solution, with linear fluorescence detection in the range of 1-200 ng of RNA. This reagent is also included with the Quant-iT RiboGreen RNA Assay Kit and comes complete with buffer and RNA standard.

Frequently asked questions (FAQs)

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.
