Best for reading 20–2,000 samples

The Quant-iT™ Kits, 1,000 assay size, provide the ultimate in convenience for DNA, RNA or protein quantitation in microplates. These are the best choice for quantitating 20–2,000 samples at a time.

The Quant-iT™ Kits for use with microplate readers include:

  • Concentrated Quant-iT™ dyes for the highest accuracy and sensitivity
  • Eight pre-diluted standards for generating the standard curve
  • Ready-to-use 1x buffer
  • Standardized protocols for automation-level efficiency, even for labs without robotics

For quantitation of more than 2,000 samples at a time, see our Quant-it™ Bulk Reagents and Kits.


Quantitation using Quant-iT™ Assay Kits
Quantitation using Quant-iT™ Assay Kits.
(Left) The Quant-iT™ dsDNA Assay Kit, High Sensitivity has a linear detection range of 0.2–100 ng and is selective for dsDNA, even in the presence of an equal mass of RNA. The x-axis gives the mass of nucleic acid when DNA or RNA is assayed alone; in the 1:1 mixture, the total mass of nucleic acid is double the amount shown. The inset shows the sensitivity of the assay for DNA. (Center) The Quant-iT™ RNA Assay Kit has a linear detection range of 5–100 ng and is selective for RNA, even in the presence of an equal mass of DNA. The x-axis gives the mass of nucleic acid when DNA or RNA is assayed alone; in the 1:1 mixture, the total mass of nucleic acid is double what is stated. (Right) The Quant-iT™ Protein Assay Kit has a detection range of 0.25–5 μg. This graph shows the signal generated from nine different proteins over the stated detection range. The protein-to-protein variability at the 3 μg point for all nine proteins assayed is 12%.

Qubit® assays for use with the Qubit® 3.0 Fluorometer

For everyday needs when quantitating 1–20 samples, use Qubit® Assays for use with the Qubit® 3.0 Fluorometer. Ideal for cloning, sequencing, transfection, qPCR, microarrays, protein gels, Western blots and protein activity assays. These kits are formulated for use with the Qubit® 3.0 Fluorometer. Also available is the Qubit® 3.0 Quantitation Starter Kit, which includes the Qubit® 3.0 Fluorometer and four Qubit® Assay Kits.
