Ethidium homodimer (EthD-1) is a high-affinity fluorescent nucleic acid dye commonly used to stain mammals, bacteria, yeast, and fungi. Ethidium homodimer binds to DNA or RNA, enhancing fluorescence more than 30 times. The Ethidium homodimer has a strong positive charge, so it cannot cross cell membranes and stain living cells; But the Ethidium homodimer can cross the disordered region of the dead cell membrane to reach the nucleus and embed the DNA double strand to produce red fluorescence. Therefore, Ethidium homodimer is a relatively sensitive nucleic acid stain that can accurately detect nucleic acids in solution or in decomposing cells. Ethidium homodimer binds DNA, Ex/Em=528/617 nm .

Propidium monoazide is a cell-impermeant photoreactive DNA-binding dye that preferentially binds to dsDNA. Propidium monoazide (PMA) prevents DNA from dead bacteria from being amplified during the PCR. PMA-PCR enhanced both the specificity and the sensitivity of PCR . Propidium monoazide is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

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 .
