Thermo Scientific NanoDrop Ultra dsDNA BR Fluorescence Assay Kit

The Thermo Scientific™ NanoDrop™ Ultra dsDNA BR (Broad Range) Fluorescence Assay Kit is a specialised quantification solution designed for use with the NanoDrop™ Ultra FL or NanoDrop Ultra^C FL spectrophotometer and fluorometer systems. This fluorescence-based assay provides accurate and selective quantitation of double-stranded DNA samples for qPCR and RT-PCR applications. The assay kit delivers broad-range quantification capabilities with linear fluorescence signals spanning DNA concentrations from 10 to 1000ng/µL. The kit includes concentrated assay reagent, dilution buffer, and DNA standards for streamlined sample preparation. The assay protocol is optimised for rapid implementation — requiring only reagent dilution, microplate loading, sample addition, mixing, and fluorescence measurement.

The NanoDrop™ Ultra platform enables rapid, precise quantification of nucleic acids and proteins in single-sample workflows while ensuring effortless 21 CFR Part 11 compliance for regulated laboratory environments when needed. Key performance characteristics include room-temperature operation with signal stability maintained for up to three hours post-preparation and robust tolerance to common laboratory contaminants, including salts, solvents, detergents, and proteins.
