Thermo Scientific™ Invitrogen™ Qubit™ RNA Broad Range (BR) Assay Kits

The Invitrogen™ Qubit™ RNA Broad Range (BR) Assay Kit is a highly accurate fluorescence-based assay designed for precise quantification of RNA across a broad concentration range. Optimized for use with Qubit Fluorometers, this assay provides reliable RNA measurements even in the presence of contaminants that can interfere with traditional absorbance-based methods.

Unlike UV spectrophotometry, which measures all nucleic acids and contaminants absorbing at 260 nm, the Qubit RNA BR Assay Kit uses highly selective fluorescent dyes that bind specifically to RNA. This ensures accurate quantification by minimizing interference from DNA, proteins, free nucleotides, salts, and solvents.

The assay is ideal for laboratories working with RNA sequencing (RNA-seq), gene expression analysis, and molecular biology workflows requiring precise RNA quantification.
