Reducing the Variability of the RiboGreen® Assay
Introduction
Ever since the approval of the Covid-19 vaccine, there has been a significant increase in interest in nucleic acid-based medications and Lipid nanoparticles (LNPs) for targeted drug delivery. With the rapid development of such systems, the development of quality characterization methods is trying to catch up and provide accurate and robust analysis techniques. Meanwhile, more traditional techniques have been deployed to help characterize some quality attributes of these drug products. One such technique is the fluorescence-based assay, RiboGreen®.
The RiboGreen® assay is a very sensitive method for evaluating the encapsulation efficiency of an LNP, but due to the multistep process required during testing, it may carry a high level of variability. This technical bulletin will provide an evaluation of the inherent variability of the assay and a comparison of data generated by two analysts and an automated system.
