Qubit RNA HS, BR, and XR Assay Kits, designed for use with Qubit Fluorometers, are highly selective for RNA over DNA, protein, and free nucleotides. All kits provide concentrated assay reagent, dilution buffer, and pre-diluted RNA standards. Simply dilute the reagent using the buffer provided, add your sample (any volume between 1 µL and 20 µL is acceptable), and read the concentration using a Qubit Fluorometer.

Qubit RNA HS Assay Kit
The Qubit RNA HS (High Sensitivity) Assay Kit, when used with the Qubit Fluorometer, provides an accurate and selective method for the quantitation of low-abundance RNA samples.  Depending on sample volume, the assay kit is designed to be accurate for initial RNA sample concentrations of 0.2 to 200 ng/µL, providing a detection range of 4−200 ng.

Qubit RNA BR Assay Kit
The Qubit RNA BR (Broad-Range) Assay Kit, when used with the Qubit Fluorometer, provides an accurate and selective method for the quantitation of RNA samples.  Depending on sample volume, the assay kit is designed to be accurate for initial RNA sample concentrations of 0.5 to 1,200 ng/µL, providing a detection range of 10−1,200 ng.

Qubit RNA XR Assay Kit
The Qubit RNA XR (Extended Range) Assay Kit, designed for use with Qubit 4 and Qubit Flex Fluorometers, provides an accurate and selective method for the quantitation of high-abundance RNA samples. Depending on sample volume, the assay kit is designed to be accurate for initial RNA sample concentrations of 5 to 20,000 ng/µL, providing a detection range of 100−20,000 ng.

Notes
• Qubit RNA HS and BR Assay kits can be used with any Qubit Fluorometer
• Qubit RNA XR Assay Kits are designed to be used only with Qubit 4 or Qubit Flex Fluorometers
• Use with thin-wall, clear, 0.5-mL PCR tubes (Cat. No. Q32856) for the Qubit 4 Fluorometer and 8 x 200-µL tube strips (Cat. No. Q33252) for the Qubit Flex Fluorometer
