RMR-Tre is a fluorescent probe targeting the mycobacterial acyltransferase Ag85. Under the catalysis of Ag85, RMR-Tre undergoes 6-position mycoloylation and anchors to the mycobacterial membrane, while achieving fluorescence activation by inhibiting the intramolecular twisted charge transfer state transition. RMR-Tre can distinguish live mycobacteria from dead ones through metabolism-driven labeling, enabling rapid, wash-free, low-background detection of viable bacteria. RMR-Tre reports the drug resistance of Mycobacterium tuberculosis via the trehalose catalytic shift activity readout associated with TreS. In addition, RMR-Tre can be combined with flow cytometry or high-content imaging techniques to visualize and quantitatively analyze the metabolic heterogeneity of Mycobacterium tuberculosis related to persistence and drug resistance. RMR-Tre is widely used in tuberculosis-related research .

BDL-E5 is a fluorescent probe for detecting live induced pluripotent stem cells at the early reprogramming stage. Its detection mechanism involves specific binding to authentic reprogramming cells, which exhibit increased expression of pluripotency and epithelial genes and decreased expression of mesenchymal genes compared to non-reprogramming cells; it appears to co-localize more significantly with the Golgi complex than other organelle markers in reprogramming cells, and it does not require washing after staining to reduce background signals; fluorescence is generated upon binding to these early reprogramming cells, with positive cells appearing 7 days before iPS colonies are visible and stain positive for the conventional pluripotent marker TRA-1-60, and sorting BDL-E5-positive cells enriches populations that generate higher numbers and quality of iPS colonies. Its detection wavelength is Ex/Em = 578/599 nm .
