AccuClear Ultra High Sensitivity dsDNA Quantitation Solution

AccuClear™ Ultra High Sensitivity dsDNA Quantitation Solution utilizes a novel, next-generation DNA binding dye for highly sensitive and accurate quantitation of purified dsDNA samples across a broad range of DNA concentrations. The assay is linear between 0.03 ng and 250 ng of dsDNA per assay in microplate format. Unlike absorbance-based measurements, AccuClear™ dye is highly selective for double-stranded DNA over single stranded DNA or RNA.

The AccuClear™ dsDNA quantitation assay is designed for fluorescence 96-well plate readers equipped with excitation and emission filters for detecting green fluorescence. The unique spectral properties of AccuClear™ dye make it especially well-suited for use with instruments with blue LED excitation sources. Biotium’s AccuLite™ 470 Mini Fluorometer (cat. no. E90001) includes a program for use with the AccuClear™ assay. AccuClear™ also is compatible with handheld fluorometers such as Invitrogen’s Qubit® and Promega’s QuantiFluor®-P, however the standard curve calibration programs for these instruments may not cover the full dynamic range of the AccuClear™ kit standard curve.

The AccuClear™ Ultra High Sensitivity dsDNA Quantitation Solution includes AccuClear™ dye and assay buffer. Biotium also offers the AccuClear™ Ultra High Sensitivity dsDNA Quantitation Kit (catalog no. 31028), which includes dye, buffer, and a set of pre-diluted calf thymus dsDNA standards. For large numbers of samples, Biotium offers the AccuClear™ Ultra High Sensitivity dsDNA Quantitation Kit with 1 DNA Standard (2000 assays, cat. no. 31029) which includes dye, 20X assay buffer, and a 25 ng/uL DNA standard stock solution that can be used to prepare a range of standards.
