WebI am a physicist by training and my research is focussed on RNA folding kinetics. We use TIRF microscopy to visualize single fluorescently labelled RNA molecules. Using smFRET we follow domain motions of (RNA) biomolecules in time. Further, we use MD simulations to understand specific RNA contacts, which are mandatory to understand RNA folding. We …
WebThree Molecular Probes® fluorogenic reagents—CellROX® Deep Red, CellROX® Green and CellROX® Orange —have been developed for the detection and quantitation of reactive oxygen species (ROS) in live cells. Each reagent is cell-permeant and is nonfluorescent or very weakly fluorescent in the reduced state. Upon oxidation, the reagents exhibit … WebWe have measured the folding/unfolding kinetics of the engineered trpzip2 peptide at different tryptophan fluorescence wavelengths, each yielding a different rate.
