Thermo Scientific NanoDrop Ultra RNA BR Fluorescence Assay Kit

The Thermo Scientific™ NanoDrop™ Ultra RNA BR Fluorescence Assay is a specialised quantitation solution engineered for precise and selective measurement of total RNA, ribosomal RNA (rRNA), and large messenger RNA (mRNA) species. This fluorescence-based assay system is specifically designed for compatibility with NanoDrop Ultra FL and Ultra^C FL spectrophotometers, delivering reliable quantitative analysis across a broad dynamic range of 10 to 1000ng/µL RNA concentrations. The assay leverages advanced fluorescence detection technology to provide linear signal response while maintaining exceptional tolerance to common laboratory contaminants, including salts, solvents, detergents, and proteins. The complete system includes concentrated assay reagent, dilution buffer, and RNA standards, enabling streamlined sample preparation through a simple dilute-load-mix-read protocol. Measurements are performed at ambient temperature with signal stability maintained for up to three hours, facilitating flexible workflow integration.

This fluorescence assay represents a key component of the NanoDrop Ultra platform's multimode detection capabilities, offering researchers enhanced sensitivity and precision for nucleic acid quantification workflows, particularly those involving quantitative PCR (qPCR) and reverse transcription PCR (RT-PCR) applications. The system provides microliter-scale analysis with 21 CFR Part 11 compliance capabilities, supporting both research and regulated laboratory environments.
