AccuClear Ultra High Sensitivity dsDNA Quantitation Kit with 7 DNA Standards



Product Description

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 use with 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 Quantiation Kit with 7 DNA Standards contains AccuClear™ dye, 1X assay buffer, and a set of seven calf thymus dsDNA standards. Note: the trial size kit includes one DNA standard solution with instructions for preparing a set of standards by serial dilution. For larger numbers of assays, Biotium also offers the AccuClear™ Ultra High Sensitivity dsDNA Quantiation Kit with 1 DNA Standard (2000 assays, catalog no. 31029), which includes AccuClear™ dye, 20X assay buffer, a calf thymus dsDNA standard solution for preparing a series of standards by serial dilution. AccuClear™ Ultra High Sensitivity dsDNA Quantitation Solution (1000 assays, catalog no. 31027), which includes dye and 1X buffer without standards, is available for customers who wish to prepare their own DNA standards.
