Description

Achieve accurate and precise quantification of dsDNA with Qubit dsDNA Assay Kits. These dsDNA quantification kits enable quick and selective detection of low and high abundance DNA samples, and can distinguish dsDNA from ssDNA, RNA, protein, and free nucleotides. Contaminants such as salts, solvents, or detergents are well-tolerated.

Qubit 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 concentrated assay reagent, dilution buffer, and pre-diluted DNA 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 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 0.005 to 120 ng/μL, providing a detection range of 0.1−120 ng.

Qubit dsDNA BR Assay Kit
The Qubit dsDNA BR (Broad-Range) Assay Kit, when used with the Qubit Fluorometer, 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 2,000 ng/μL, providing a detection range of 4−2,000 ng.

Notes
• Qubit dsDNA HS and BR Assay kits can be used with any Qubit Fluorometer
