1. Introduction RNA quantification is a fundamental step in molecular biology workflows, ensuring accurate input for downstream applications such as RT-qPCR, RNA-seq, and microarray analysis. Traditional spectrophotometric methods, such as Nanodrop, often overestimate RNA concentrations due to the presence of contaminants. The Qubit RNA HS Assay Kit overcomes this limitation by using selective fluorometric dyes that bind specifically to RNA, providing superior accuracy and reproducibility.

2. Principles of the Qubit RNA HS Assay The RNA HS Assay Kit for Qubit relies on a fluorescence-based detection system that selectively binds RNA, minimizing interference from DNA and other contaminants. The workflow includes:

• Sample Preparation: Diluting the RNA sample in an optimized assay buffer.
• Fluorescent Dye Binding: Adding the HS reagent, which selectively binds RNA.
• Fluorescence Measurement: Using the Qubit fluorometer to quantify RNA concentration.
• Data Interpretation: Generating an accurate RNA concentration range with high specificity.
