The Qubit RNA XR (Extended Range) Assay Kit, when used with the Qubit Fluorometer, provides an accurate and selective method for the quantitation of high-abundance RNA samples. The assay is highly selective for RNA and does not quantitate DNA, protein, or free nucleotides. Common contaminants, such as salts, free nucleotides, solvents, detergents, and protein, are well-tolerated in the assay. The assay kit is designed to be accurate for initial RNA sample concentrations from 1 ng/µL to 8 µg/µL, providing an assay range from 20 ng –8 µg. The kit provides concentrated assay reagent, dilution buffer, and pre-diluted RNA standards. Simply dilute the reagent using the buffer provided, add the sample (any volume between 1 µL and 20 µL is acceptable), and read the concentration using a Qubit 2.0, 3, or 4 fluorometer.

1. The Qubit RNA XR Assay works on Qubit 2.0, 3, and 4 fluorometers. It will not work on the original Qubit 1.0 Fluorometer. Download the MyQubit .qbt file for the Qubit 2.0 or 3 fluorometer.
2. The Qubit RNA XR Assay Kit replaces the Qubit RNA BR (broad-range) Assay Kit.
3. 500-mL thin-walled PCR tubes (Cat. No. Q32856) are required but not included.

For Research Use Only. Not for use in diagnostic procedures.
