Bacteria

Ruthenium Red (Ammoniated ruthenium oxychloride) is a polycationic dye widely used for electron microscopy (EM) of cells, tissues and vegetative bacteria. Ruthenium red strongly reacts with phospholipids and fatty acids and binds to acidic mucopolysaccharides. Ruthenium red is a L-type calcium current (ICa) blocker, blocks Ca2+ uptake and release, and voltage-sensitive Ca2+ channels

Resazurin sodium (Resazurin sodium salt) salt is a blue non-fluorescent dye,is widely used as a metabolic indicator for living cells

Crystal Violet (Hexamethylpararosaniline chloride) is a triarylmethane dye that is a mixture of violet rosanilinis, with antibacterial, antifungal, and anthelmintic properties.

Rose Bengal sodium is a potent inhibitor of VGlut and vesicular monoamine transporter (VMAT) (Ki of 19 and 64 nM for VGlut andVMAT, respectively）

Merbromin (Mercury dibromofluorescein disodium salt) is an organomercuric disodium salt compound and a fluorescein, used as a topical antiseptic for minor cuts and scrapes.

Acridine Orange base is a cell-permeable fluorescent dye that binds to nucleic acids and emits different colors of fluorescence, which exhibits green fluorescence when bound to dsDNA (Ex=488 nm, Em=520-524 nm) and red fluorescence when bound to ssDNA or ssRNA (Ex=457 nm, Em=630-644 nm) and can be used for cell cycle analysis and apoptosis detection.

Lucigenin (NSC-151912) (L-6868) is a chemiluminescent probe used to indicate the presence of endogenously generated superoxide anion radicals in cells.

Brilliant blue G-250 (Acid blue 90, Coomassie Brilliant Blue G) is an antagonist of the P2X7 purinergic receptor.

Methyl blue is a triaminotriphenylmethane dye. It is used as an antiseptic dye in the polychrome staining method and has applications in histological and microbiological staining solutions.

Pyronine B (NSC 44690) is a fluorophore with low relative fluorophore brightness and a small hydrophobic (SH) protein channel inhibitor, which is used for staining of bacteria and mycobacteria and in the spectrophotometric determination of ultra-trace ruthenium.

6-CFDA N-succinimidyl ester (Carboxyfluorescein diacetate succinimidyl) is capable of spontaneously and irreversibly binding to free amines. Utilized in flow cytometry experiments for tracking cell division in both mammalian cells and bacteria. Used in combination with several cell permeabilizers as an effective, nondestructive fluorescencent stain to quickly detect bacterial cells.

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.

Methyl Green Zinc Chloride, a potent fluorescent dye, is utilized for staining DNA in cells and electrophoretic gels. It serves as a direct measure of viability through microscopy and flow cytometry, exhibiting peaks at 633 and 677 nm [1] [2]. For storage, it should be protected from light.

Rf470DL, a rotor-fluorogenic D-amino acid (RfDAA), serves as a bacterial labeling agent, exhibiting an excitation wavelength (Ex) of 470 nm and an emission wavelength (Em) of 640 nm [1].

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].

Reactive Blue 19 is a useful organic compound for research related to life sciences. The catalog number is T64813 and the CAS number is 2580-78-1.

3,3'-Diethylthiacyanine iodide, a cyanine fluorescent dye, exhibits a significant affinity for bacterial cells [1].

Wright's stain is a useful organic compound for research related to life sciences and the catalog number is T65498.

Alcian blue is a copper-containing dye used as a gelling agent for lubricants, for staining of bacteria and for the dyeing of histiocytes and fibroblasts in vivo.

Auramine hydrochloride is an aniline dye. Auramine hydrochloride is used as a disinfectant and an antiseptic agent.

C.I. 74240 is a copper-containing dye used as a gelling agent for lubricants, for staining of bacteria and for the dyeing of histiocytes and fibroblasts in vivo.
