BADAN is a thiol-reactive, environment-sensitive fluorescent probe used for site-specific labeling of protein cysteine residues to detect protein topology, local polarity, protein-lipid interactions, and conformational changes. The bromoacetyl group of BADAN covalently binds to cysteine thiols, and its fluorescence originates from the intramolecular charge transfer (ICT) excited state. The emission peak position varies with the polarity of the surrounding medium: it blue-shifts to approximately 488 nm in nonpolar environments (such as the hydrophobic core of lipid bilayers) and red-shifts to approximately 496-507 nm in polar environments (such as aqueous phases), independent of enzymes, pH, or membrane potential. Ex = 380-402 nm; Em = 400-600 nm .

Leucocrystal violet-d6 is the deuterium labeled Leucocrystal violet (HY-D0233). Leucocrystal violet is a cationic triarylmethane dye. Leucocrystal violet generates a colored purple product in the presence of hydrogen peroxide and horseradish peroxidase, or when oxidized by periodate under the catalysis of horseradish peroxidase. Leucocrystal violet serves as a chromogenic reagent for the determination of submicrogram-level hydrogen peroxide, with no interference from tryptophan, persulfate or chromate. Leucocrystal violet reacts with blood to produce a purple/violet color in the presence of hydrogen peroxide; it forms a very weak fluorophore when acting with whole blood in an unbuffered solution, with a maximum absorption wavelength of 630 nm and a maximum fluorescence emission wavelength of 665 nm upon excitation at 630 nm.

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.
