Highly selective for dsDNA over RNA, the Qubit 1X dsDNA HS and BR Assay Kits offer easy-to-use formulations for the accurate quantitation of dsDNA in 100 and 500 assay formats. Lambda Standards provide sufficient material for up to 500 samples. 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. Qubit™ 1X dsDNA High Sensitivity (HS) and Broad Range (BR) Assay Kits. Highly selective for dsDNA over RNA, the Qubit 1X dsDNA HS and BR Assay Kits offer easy-to-use formulations for the accurate quantitation of dsDNA in 100 and 500 assay formats. 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. The Qubit® dsDNA HS (High Sensitivity) Assay Kits make DNA quantitation easy and accurate. The kits include concentrated assay reagent, dilution buffer, and prediluted DNA standards. To determine the purity of your sample, use the Qubit® RNA HS Assay Kit together with the Qubit® dsDNA HS Assay Kit. These measurements give you a much better indication of sample purity than that produced by measuring the A260/A280 ratio. Achieve accurate and precise quantification of double-stranded DNA with Qubit dsDNA HS and BR 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. The QubitTM dsDNA HS (High Sensitivity) Assay Kits make DNA quantitation easy and accurate. The assay is highly selective for double-stranded DNA (dsDNA) over RNA (see “Assay selectivity” on page 2). 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. 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.
