Stains-All is a cationic dye of carbocyanine.

Azure B (Azure B chloride) is a cationic dye and the major metabolite of Methylene blue. Azure B is a selective, and reversible inhibitor of MAO-A (IC50s: 11 and 968 nM for recombinant human MAO-A and MAO-B).

FM4-64 (SynaptoRed™ C2) is a styrene-based dye exhibiting membrane-binding and endocytosis tracing properties, yet it remains largely non-fluorescent in aqueous solutions. After binding to the plasma membrane bilayer, FM4-64 cannot passively diffuse into the cell interior and must undergo active transport across the membrane. FM4-64 can be used to study endocytosis, exocytosis, vesicular transport, and cell membrane dynamics.

4-Di-1-ASP is a positively charged fluorescent dye used to label glioma cells in live brain tissue and can also be used to observe mitochondria in live cells, with λex/λem = 475/606 nm.

Safranin O (Basic red 2) stains the lignified, embolic and keratinized parts of the plant, as well as chromatin and chromosomes in the nucleus. Safranin O is commonly used for the detection of cartilage, mucin and mast cell granules.

Hoechst stains are part of a family of blue fluorescent dyes used to stain DNA. HOE 33187 is a cell dye for DNA. Hoechst dyes are soluble in water and in organic solvents such as dimethyl formamide or dimethyl sulfoxide. Concentrations can be achieved of

Hoechst 33258 analog 5 is a DNA minor groove binding fluorescent dye. It binds A/T-rich regions with strong blue emission, used for nuclear imaging and cell cycle quantification in flow cytometry.

Hoechst 33258 analog 6 is an analog of Hoechst stains which are part of a family of blue fluorescent dyes used to stain DNA.

Hoechst stains are part of a family of blue fluorescent dyes used to stain DNA.

Fluorescent brightener 28 (Technical Grade) is commonly utilized as a fluorescent whitening agent in the textile industry, particularly for dyeing fibers such as cellulose and other polysaccharides during the padding process. When the plasma membrane is disrupted, it weakly stains the cytoplasm and strongly stains the nucleus. Additionally, it can be employed in detecting chitin in live cells. Fluorescent brightener 28 also serves as a photosensitive light initiator for visible light-emitting diodes (LEDs) in radical photopolymerization.

Alizarin complexone dehydrate is the dihydrate form of Alizarin complexone. Alizarin complexone is a calcium-binding fluorescent dye that stains mineralization areas of bones by binding to calcium crystals. It inhibits reverse transcriptase activity of RAV-2, HIV-1, and RSV with IC50 values of 3.8 μg/mL, 45 μg/mL, and 100 μg/mL, respectively. Alizarin complexone also exhibits antiviral properties against HIV-1 and RSV and delays tumor induction by RSV in chickens.

Hoffman's violet is specific stains for animal chromosomes. Iodinated alcohol after staining can be substituted with various acids, both organic as well as inorganic, all of which act as trapping agent preventing leaching of the dye that binds with the ch

Coelenterazine hcp is a synthetic bioluminescent luciferin that displays an emission maximum of 445 nm.1It has been used as a calcium indicator and substrate to quantifyRenillaluciferase activity.1,2,3 1.Sabnis, R.W.Handbook of biological dyes and stains: Synthesis and industrial applications(2010) 2.Shimomura, O., Kishi, Y., and Inouye, S.The relative rate of aequorin regeneration from apoaequorin and coelenterazine analoguesBiochemistry Journal296(Pt 3)549-551(1993) 3.Pichler, A., Prior, J.L., and Piwnica-Worms, D.Imaging reversal of multidrug resistance in living mice with bioluminescence: MDR1 P-glycoprotein transports coelenterazineProc.

TPE-MI (Tetraphenylethene maleimide) is an aggregation-induced luminescent agent that stains living cells, can be used to capture cysteines in exposed unfolded proteins, and detects protein damage after dihydroartemisinin studies of malaria parasites.

DIBA-Cy5, a fluorescent DIBA antagonist, consists of DIBA-alkyne and Cyanine5 fluorophores (Cy5) linked by a polyethylene glycol (PEG) chain. It functions as a fluorescent ligand for probe attachment via click chemistry, exhibiting high binding affinity to type-2 mAChR (M2R) with a dissociation constant (Kd) of 1.80 nM. Notably, DIBA-Cy5 effectively stains M2R receptors in the sinoatrial node of mouse hearts [1].

DASPEI, a cationic styrenyl mitochondrial dye, is characterized by a large Stokes shift and excitation/emission wavelengths at 550/573 nm, yielding robust chromogenic properties. It effectively stains mitochondria in live cells and labels presynaptic nerve endings regardless of neuronal activity [1].

4-Di-10-ASP, a fluorescent lipophilic tracer (Excitation 485 nm; Emission 620 nm), specifically stains phospholipid membranes [1] [2].

Azure A (chloride), a phenothiazine dye, is produced through the oxidation of methylene blue and exhibits strong metachromatic properties. This compound is useful in studying stains and serves as a redox medium in electrochemical biosensing applications [1] [2].

JF526-Taxol (TFA) serves as a versatile scaffold for fluorogenic probes, including ligands for self-labeling tags, stains for endogenous structures, and spontaneously blinking labels for super-resolution immunofluorescence [1].

LipidGreen 2, a second-generation small molecule probe for lipid imaging, offers an enhanced fluorescence signal compared to the original LipidGreen. It selectively stains neutral lipids in cells and fat deposits in live zebrafish [1].

DiI iodide1 is one of lipophilic fluorescent stains for labeling membranes and other hydrophobic structures. The fluorescence of these environment-sensitive dyes is greatly enhanced when incorporated into membranes or bound to lipophilic biomolecules such as proteins although they are weakly fluorescent in water.
