Published Workflows
Objective: Validate scatter-free absorption spectroscopy as a method for accurate total RNA quantification in complex intact RNA nanoparticle formulations and compare its performance with fluorescence-based assays.
Why it works: The abstract states that SFAS removes light scattering from nanoparticle components, a source of interference in complex formulations, and then compares SFAS outputs against fluorescence-based assays across diverse formulation types.

Stages
- 1.Diverse formulation panel selection(selection)
The abstract says the method was validated using multiple formulation classes specifically because these characteristics can interfere with RNA quantification.
Selection: Use diverse RNA formulations with physicochemical characteristics that can interfere with RNA quantification.
- 2.Comparator assay benchmarking(confirmatory_validation)
The abstract explicitly frames the study as validation of SFAS by comparison to established fluorescence-based assays.
Selection: Compare SFAS measurements with fluorescence-based assays using RiboGreen and SYTO 9.
