Project title: Photoconversion of Nuclear Probes
Project description (50-100 words suggested): Fluorescent nuclear probes have been shown to convert from fluorescent blue to fluorescent green upon excitation with UV light and 405 nm laser light. This photoconversion can lead to artifacts in images containing green fluorescent labels leading to overestimates of green intensities and false positives for nuclear localization of green fluoescent probes. This project will involve testing different UV and 405 nm excitation powers to determine if there is a critical time or intensity threshold important for this photoconversion from blue to green to occur. The end result will be a set of recommendations for scientists using these blue nuclear dyes so they can ensure they do not induce this photobleaching artifact during standard fluorescence imaging.
