Product Description

The AccuBlue® Broad Range dsDNA Quantitation Solution offers sensitive and selective detection of purified dsDNA samples with minimal effects from common contaminants.  The assay provides a linear detection range from 2 – 2000 ng and is designed for use with fluorescence microplate readers. This solution does not come with a DNA standard; see the AccuBlue® Broad Range Kit (31007) which contains a set of calf thymus DNA standards.

Fluorescence-Based dsDNA Quantitation

AccuBlue®, AccuClear® and AccuGreen™ dsDNA quantitation assays allow precise quantitation of purified dsDNA samples across a wide range of concentrations and a variety of fluorescence detection instruments. Unlike absorbance-based nucleic acid quantitation, fluorescent DNA binding dyes are highly sensitive and selective for double-stranded DNA and provide a more accurate DNA concentration in the presence of contaminating RNA and other common contaminants including free nucleotides, protein, detergents and salts.

Biotium offers dsDNA quantitiation kits and solutions for different instruments and sample concentration ranges. See the table below and visit the DNA & RNA Quantitation Technology Page for details on our full line of dsDNA and RNA quantitation kits.
