Thermo Scientific™ Invitrogen™ Qubit™ RNA Extended Range (XR) Assay Kits

The Invitrogen™ Qubit™ RNA Extended Range (XR) Assay Kit is a fluorescence-based quantification solution designed for accurate measurement of high-abundance RNA samples. Specifically optimized for use with the Qubit™ 4 and Qubit™ Flex Fluorometers, this assay provides precise and selective RNA quantification across an extended dynamic range, enabling reliable measurement of concentrated RNA samples without the need for repeated dilution.

Using highly selective fluorescent dyes that bind specifically to RNA, the Qubit RNA XR Assay Kit ensures accurate results even in the presence of contaminants such as DNA, proteins, salts, solvents, and detergents. This makes it ideal for high-concentration RNA workflows in genomics, transcriptomics, and molecular biology research.

The assay is particularly useful for applications involving RNA sequencing, gene expression analysis, and RNA sample preparation workflows requiring precise quantification of high-concentration RNA.
