Quinacrine mustard hydrochloride is a fluorescent dye and polycyclic aromatic agent that acts as a mutagen to induce mutants in bacteria.Quinacrine mustard hydrochloride selectively binds to adenine-thymine (AT) base pairs, but not to guanine-cytosine (GC). Quinacrine mustard (hydrochloride) selectively binds to adenine-thymine (AT) base pairs rather than to guanine-cytosine (GC) base pairs, inducing cell cycle arrest at G2 M. Quinacrine mustard (hydrochloride) has been used to label chromosomes for karyotyping by autoradiography.

Giemsa stain, used in histology and microbiology, can stain chromatin and the nuclear membrane. It is employed in histopathology to detect malaria and other microorganisms, such as Histoplasma, Leishmania, Toxoplasma, and Pneumocystis [1].

5-InoAz serves as a metabolic probe for labeling the mycobacterial cell envelope. It is specifically engineered as an inositol analog to integrate into cell envelope glycolipids [phosphatidylinositol mannoside (PIM), PIM-anchored lipomannan (LM), and lipoarabinomannan (LAM)]. Coupled with bioorthogonal chemistry, it offers a valuable tool for examining the biosynthesis, transport, and dynamics of PIM, LM, and LAM in various mycobacterial species.
