Fluorescence-Based Nucleic Acid Quantitation
Fluorescence-based nucleic acid quantitation assays allow precise quantitation of purified dsDNA or RNA samples across a wide range of concentrations and a variety of fluorescence detection instruments.
Unlike absorbance-based nucleic acid quantitation, which cannot distinguish between DNA, RNA, and free nucleotides, fluorescent assays are highly selective for either dsDNA or RNA. Fluorescent assays also allow more sensitive detection of low concentrations of DNA or RNA, allowing you to preserve your precious samples.
Biotium offers dsDNA quantitiation kits and solutions for different instruments and sample concentration ranges. Some of our kits offer unrivaled sensitivity or linear ranges.
Biotium also offers an RNA quantitation kit with the widest linear range on the market and multi-instrument capability, making it the most convenient assay you will find.
Microplate reader dsDNA assay features
- Allow quantitation of many samples and replicates at once, for better accuracy
- Microplate readers have the highest sensitivity and adjustable excitation and emission settings
- The AccuBlue® NextGen assay is the most sensitive DNA quantitation assay on the market, allowing accurate detection of 1 pg* of DNA
- The AccuClear® assay is extremely versatile, with a very broad dynamic range, allowing quantitation of nearly any sample
