Coomassie (also known as Brilliant Blue, Brilliant Blue G, Acid Blue 90, C.I. 42655, or Brilliant Blue G 250) is a blue dye commonly used in sodium dodecyl sulfate polyacrylamide gel electrophoresis. The gel is soaked in dye for thirty minutes and then destained for thirty minutes or more. This treatment allows the visualization of bands indicating the protein content of the gel. The visualization on the gel usually contains a set of molecular weight marker so that protein MW can be determined in an unknown solution. ...more on Wikipedia about "Coomassie"
Cyto-Stain, or CytoStain, is commercially available mix of staining dyes for polychromatic staining in histology. It provides results comparable to Papanicolaou staining, but in less number of operations and in shorter time. It is used in ultrafast Papanicolaou staining. ...more on Wikipedia about "Cyto-Stain"
DAPI or 4',6-diamidino-2-phenylindole is a fluorescent stain that binds strongly to DNA. It is used extensively in fluorescence microscopy. Since DAPI will pass through an intact cell membrane, it may be used to stain live and fixed cells. ...more on Wikipedia about "DAPI"
Eosin is an orange-pink dye derived from coal tar. It can be used to stain cytoplasm, collagen and muscle fibers for examination under the microscope. ...more on Wikipedia about "Eosin"
Ethidium bromide (EtBr) is an intercalating agent commonly used as a nucleic acid stain in molecular biology laboratories for techniques such as agarose gel electrophoresis. When exposed to ultraviolet light, it will fluoresce with a red-orange color, intensifying almost 20-fold after binding to DNA. This is likely not due to rigid stabilization of the phenyl moiety, because the phenyl ring has been shown to project outside the intercalated bases. The increased hydrophobicity of the environment is believed to be responsible. Because it binds to DNA, ethidium bromide is a very strong mutagen, and may possibly be a carcinogen or teratogen. ...more on Wikipedia about "Ethidium bromide"
The dye Ethyl Green (Brilliant Green, C.I. 42590; C27H35N3ClBr), due to its powerful bacteriostatic properties, is commonly used along with iodine tincture as a topical antiseptic in Eastern Europe / the former USSR (common name: Zelyonka / Зелёнка), though not in the west due to its irritant properties and toxicity if ingested. It is soluble in water. ...more on Wikipedia about "Ethyl Green"
Fast Green FCF, also called Food green 3, FD&C Green No. 3, Green 1724, Solid Green FCF, and C.I. 42053, is a sea green triarylmethane food dye. Its E number is E143. ...more on Wikipedia about "Fast Green FCF"
Fluorescein is a fluorophore commonly used in microscopy, in a type of dye laser as the gain medium, and in forensics and serology to detect latent blood stains. ...more on Wikipedia about "Fluorescein"

Fuchsine, fuchsin, rosanilin, or rosaniline hydrochloride is a magenta dye with chemical formula 19 17 3· . It becomes magenta when dissolved in water; as a solid, it forms dark green crystals. Its inventor, the 19th century French company Renard, named the dye after the German translation of the company's name, fuchs ( fox). ...more on Wikipedia about "Fuchsine"
Haematoxylin, hematoxylin, Natural Black 1, or C.I. 75290 is extracted from the wood of the logwood tree. When oxidised it forms haematein, a compound with rich blue-purple colour, and is used, together with a suitable mordant (most commonly Fe(III) or Al(III) salts), to stain cell nuclei prior to examination under a microscope. Structures that stain with haematoxylin are called basophilic. ...more on Wikipedia about "Haematoxylin"
The Hoechst stains are part of a family of fluorescent stains for labelling DNA in fluorescence microscopy. Two of these closely related bis-benzimides are commonly used: Hoechst 33258 and Hoechst 33342. ...more on Wikipedia about "Hoechst stain"
Iodine (from the Gr. Iodes, meaning "violet"), is a chemical element in the periodic table that has the symbol I and atomic number 53. It is required as a trace element for most living organisms.

Methyl violet is the name given to a group of similar chemicals used as pH indicators and dyes. Methyl violets are mixtures of tetramethyl, pentamethyl and hexamethyl pararosanilins. By blending the different versions, the dyemaker can create different shades of violet in the final dye. The more methylated the compound (the more methyl groups attached), the deeper blue the final color will be. ...more on Wikipedia about "Methyl violet"
