Qubit 1X dsDNA HS and BR Assay Kits, designed for use with Qubit Fluorometers, are highly selective for double-stranded DNA (dsDNA) over single-stranded DNA (ssDNA), RNA, protein, and free nucleotides. All kits provide a ready-to-use working solution and DNA standards. To perform the assay, simply dilute your sample (any volume from 1–20 μL is acceptable) into the 1X working solution provided, then read the concentration using a Qubit Fluorometer.

Qubit 1X dsDNA HS Assay Kit
The Qubit dsDNA HS (High Sensitivity) Assay Kit, when used with the Qubit Fluorometer, provides an accurate and selective method for the quantitation of sensitive DNA samples. Depending on sample volume, the assay kit is designed to be accurate for initial DNA sample concentrations of 5 pg/μL to 120 ng/μL, providing a detection range of 0.1−120 ng.

Qubit 1X dsDNA BR Assay Kit
The Qubit dsDNA BR (Broad-Range) Assay Kit, designed for use with Qubit 4 or Qubit Flex Fluorometers, provides an accurate and selective method for the quantitation of DNA samples. Depending on sample volume, the assay kit is designed to be accurate for initial DNA sample concentrations of 0.2 to 4,000 ng/μL, providing a detection range of 4-4,000 ng.

Notes
• Qubit 1X dsDNA HS can be used with Qubit 2, Qubit 3, Qubit 4, and Qubit Flex Fluorometers
• Qubit 1X dsDNA BR are designed for use with Qubit 4 and Qubit Flex Fluorometers
• Use 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
