Technology description follows. <HD SOURCE="HD1">Reversibly Photo-Switchable Fluorescent Proteins for Long-Term Imaging of Live Specimen</HD> Available for research uses, collaboration, and further development are non-cytotoxic reversibly photo-switchable fluorescent mutant proteins that may be locked in a state of high brightness, which may be useful for long-term biomedical applications at routine laser power intensity. Additionally, these proteins offer quick self-recovery of peak fluorescence, which may be useful for imaging of rapid cellular processes. <HD SOURCE="HD2">Inventors</HD> <FP SOURCE="FP-1">• Vitaly Boyko, Ph.D. (NIBIB)</FP> <FP SOURCE="FP-1">• George Patterson, Ph.D. (NIBIB)</FP> <FP SOURCE="FP-1">• Md Abdul Kader Sagar, Ph.D. (NIBIB)</FP> <HD SOURCE="HD2">Potential Applications</HD> <FP SOURCE="FP-1">• Long-term imaging of live specimen, including light-sensitive specimen</FP> <FP SOURCE="FP-1">• Probe for high-throughput screening applications</FP> <FP SOURCE="FP-1"> • Fluorescent marker in biomedical screening protocols </FP> <FP SOURCE="FP-1">• Diagnostic tool for cytotoxicity or component of diagnostic kit that utilizes fluorescent proteins.</FP> <HD SOURCE="HD2">Licensable Materials</HD> <FP SOURCE="FP-1">• The nucleotide sequences of fluorescent protein</FP> <FP SOURCE="FP-1">• Fusion construct to LC3A autophagy marker protein or mitochondria targeted peptide.</FP> <SIG> <DATED>Dated: June 10, 2025.</DATED> <NAME>Michael A.
