Amiscience's dsDNA quantitation assays allow precise quantitation of purified dsDNA samples across a wide range of concentrations. By using with our FluroQuik handheld fluorometer, 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. We offer three dsDNA quantitiation kits for different instruments and sample concentration ranges. The kits also differ in their tolerance of various contaminants.The Ultra High Sensitivity assay is based on a novel, next-generation DNA binding dye which offers unrivaled sensitivity and dynamic range compared to other DNA dyes.
