The Qubit dsDNA BR Assay Kit is designed specifically for use with the Qubit Fluorometer. The assay is highly selective for double-stranded DNA (dsDNA) over RNA and is designed to be accurate for initial sample concentration from 100 pg/µl–1,000 ng/µl. The kit provides 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 the Qubit Fluorometer. Common contaminants, such as salts, free nucleotides, solvents, detergents, or protein are well tolerated in the assay.
