Webb15 sep. 2024 · The Ribogreen® assay found values that are deviating more from the values of the other methods and also has a very high standard deviation between repeated measurements. These two findings may be related, but in our hands, the Ribogreen® assay failed to produce reproducible results and is clearly the outlier in this study. RiboGreen is a proprietary fluorescent dye that is used in the detection and quantification of nucleic acids, including both RNA and DNA. It is synthesized and marketed by Molecular Probes/Invitrogen (a division of Life Technologies, now part of Thermo Fisher Scientific) of Eugene, Oregon, United States. In its free form, RiboGreen exhibits little fluorescence and possesses a negligible absorbance signature. When bound to nucleic acids, the dye fluoresces with an intensity that, ac…
