DNA Quantitation Kits
What are the differences between the DNA quantitation kits? Which should I choose?

AccuGreen™ kits are designed for use with the Qubit® fluorometer. All of the other kits are designed for use with 96-well fluorescence plate readers. Our quantitation kits vary in the concentration ranges of dsDNA that they are able to detect. Some of the kits also have different fluorescence excitation/emission. Visit the DNA Quantitation Kit Technology Page or consult the table below to make your selection.

← FAQs
What instruments can I use with your DNA quantitation kits? Do they work on Qubit®?

The AccuClear® and AccuBlue® DNA Quantitation kits are designed for use with fluorescence 96-well plate readers. AccuClear®, AccuBlue® NextGen and AccuBlue® High Sensitivity kits require an instrument equipped to read green fluorescence emission (similar to FITC). AccuBlue® Broad Range requires an instrument equipped to read blue fluorescence emission (Ex/Em 350/460 nm).

These assays also can be used with fluorometers such as the Qubit® (Thermo Scientific) and QuantiFluor™-P (Promega). However, due to different linear ranges of the assays, not all of these assays are compatible with the pre-programmed DNA quantitation programs on these instruments. For users who own a Qubit® fluorometer, we recommend using our AccuGreen™ kits, which are designed for use on that instrument.

The AccuGreen™ High Sensitivity DNA Quantitation kit is designed for use on the Qubit® fluorometer. It can be used in the preprogrammed Qubit® dsDNA High Sensitivity assay, and is a direct replacement for the Qubit® dsDNA HS Assay kit.

The AccuGreen™ Broad Range DNA Quantitation kit is designed for use on the Qubit® fluorometer. It can be used in the preprogrammed Qubit® dsDNA Broad Range assay, and is a replacement for the Qubit® dsDNA BR Assay kit.

Which kits are the best alternatives for ThermoFishers Quant-iT™ and Qubit® kits?

For detection of picogram levels of DNA on a microplate reader, we recommend our AccuBlue® NextGen dsDNA Quantitation Kit (detection range 2.5 pg-3 ng dsDNA) which has higher accuracy and sensitivity than PicoGreen® in a 96-well assay format.

Also see our AccuClear® Ultra High Sensitivity dsDNA Quantation Kit, which is a great all-purpose choice: it has high sensitivity with a broad linear detection range (30 pg-250 ng dsDNA).

If you own a Qubit® fluorometer, we recommend our AccuGreen™ kits, which were designed for use with the Qubit® fluorometer.  AccuGreen™ High Sensitivity dsDNA Quantitation kit is a direct replacement for the Qubit® dsDNA HS Assay kit. AccuGreen™ Broad Range dsDNA Quantitation Kit is a replacement for the Qubit® dsDNA BR Assay kit.

Note that the lower limits of kit sensitivity may depend on the detection instrument used.
