SILVER NITRATE (7761-88-8)  
Alcoholic Silver Nitrate  ·  Silver Nitrate, Silver (2+) Salt (2:1)
Silver nitrate is an inorganic compound with chemical formula AgNO 3. This compound is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides.
OSMIUM TETROXIDE (20816-12-0)  
Osmic Acid
Osmium tetroxide (also osmium(VIII) oxide) is the chemical compound with the formula OsO4. The compound is noteworthy for its many uses, despite its toxicity and the rarity of osmium. It also has a number of interesting properties, one being that the solid is volatile.
methylene blue (61-73-4)  
Methylthionine Chloride  ·  Methylene Blue N  ·  Urolene Blue
Methylene blue, also known as methylthioninium chloride, is a medication and dye. As a medication, it is mainly used to treat methemoglobinemia. Specifically, it is used to treat methemoglobin levels that are greater than 30% or in which there are symptoms despite oxygen therapy.
4-Aminoazobenzene (25548-34-9, 60-09-3)  
aniline yellow  ·  para-Aminoazobenzene  ·  para Aminoazobenzene
Azobenzene is a chemical compound composed of two phenyl rings linked by a N=N double bond. It is the simplest example of an aryl azo compound. The term 'azobenzene' or simply 'azo' is often used to refer to a wide class of molecules that share the core azobenzene structure, with different chemical functional groups extending from the phenyl rings.
fluorescein (2321-07-5, 518-45-6)  
Sodium Fluorescein  ·  Fluorescein Sodium  ·  Uranine
Fluorescein is a manufactured organic compound and dye. It is available as a dark orange/red powder slightly soluble in water and alcohol. It is widely used as a fluorescent tracer for many applications.
AURAMINE (492-80-8)  
Auramine O  ·  Benzophenoneidum
MALACHITE GREEN (569-64-2, 13425-25-7)  
basic green 4  ·  (4-(4-(dimethylamino) alpha-phenylbenzylidene)-2,5- cyclohexadien-1-ylidene)dimethylammonium chloride  ·  C.I. 42000
Malachite green is an organic compound that is used as a dyestuff and controversially as an antimicrobial in aquaculture. Malachite green is traditionally used as a dye for materials such as silk, leather, and paper. Despite its name the dye is not prepared from the mineral malachite, and the name just comes from the similarity of color.
Fast Green FCF (2353-45-9)  
Green No. 3  ·  Food Green 3  ·  F D and C Green No. 3
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.
ETHIDIUM BROMIDE (1239-45-8)  
Ethidium  ·  Homidium Bromide  ·  Novidium
Ethidium bromide is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis. It is commonly abbreviated as "EtBr", which is also an abbreviation for bromoethane. When exposed to ultraviolet light, it will fluoresce with an orange colour, intensifying almost 20-fold after binding to DNA.
Congo red (573-58-0)  
Congo red is an organic compound, the sodium salt of 3,3′-([1,1′-biphenyl]-4,4′-diyl)bis(4-aminonaphthalene-1-sulfonic acid. It is an azo dye. Congo red is water-soluble, yielding a red colloidal solution; its solubility is greater in organic solvents.
RHODAMINE B (81-88-9)  
rhodamine B dihydride  ·  tetraethylrhodamine  ·  rhodamine B acetate
Rhodamine B is a chemical compound and a dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with instruments called fluorometers.
Acid Green 5 (5141-20-8)  
Light green SF  ·  C.I. 42095  ·  food green 2
Light Green SF (C.I. 42095) is a green triarylmethane dye.
Brilliant green (633-03-4)  
ethyl green  ·  (4-(4-(diethylamino)-alpha-phenylbenzylidene)-2,5-cyclohexadien-1-ylidene)diethylammonium sulfate  ·  (4-(p-(diethylamino)-alpha-phenylbenzylidene)-2,5-cyclohexadien-1-ylidene)diethylammonium sulfate
Brilliant Green may refer to: The Brilliant Green, Japanese rock band The Brilliant Green (album), the band's eponymous debut album Brilliant green (dye), a dye and antiseptic
HEMATOXYLIN (517-28-2, 17647-60-8)  
Haematoxylon  ·  Hemotoxylin  ·  Hydroxybrazilin
Haematoxylin or hematoxylin (), also called natural black 1 or C.I. 75290, is a compound extracted from the heartwood of the logwood tree (Haematoxylum campechianum). Haematoxylin and eosin together make up haematoxylin and eosin stain, one of the most commonly used stains in histology.
Haematoxylin (517-28-2)  
Hematoxylin  ·  Haematoxylon  ·  Hemotoxylin
Haematoxylin or hematoxylin (), also called natural black 1 or C.I. 75290, is a compound extracted from the heartwood of the logwood tree (Haematoxylum campechianum). Haematoxylin and eosin together make up haematoxylin and eosin stain, one of the most commonly used stains in histology.
4-Dimethylaminocinnamaldehyde (20432-35-3, 6203-18-5)  
p-dimethylaminocinnamaldehyde  ·  trans-4-(N,N-dimethylamino)cinnamaldehyde  ·  4-DACA
Acridine orange (10127-02-3, 494-38-2)  
Acridine Orange Base  ·  Rhoduline Orange  ·  Basic Orange 3RN
Acridine orange is an organic compound. It is used as a nucleic acid-selective fluorescent cationic dye useful for cell cycle determination. Being cell-permeable, it interacts with DNA and RNA by intercalation or electrostatic attractions respectively.
propidium iodide (25535-16-4)  
Propidium  ·  Propidium Diiodide
Propidium iodide (or PI) is a fluorescent intercalating agent that can be used to stain cells. Propidium iodide is used as a DNA stain in flow cytometry to evaluate cell viability or DNA content in cell cycle analysis, or in microscopy to visualise the nucleus and other DNA-containing organelles. Propidium Iodide cannot cross the membrane of live cells, making it useful to differentiate necrotic, apoptotic and healthy cells.
5-Ethynyl-2'-deoxyuridine (61135-33-9)  
5-Ethynyl-2´-deoxyuridine (EdU) is a thymidine analogue which is incorporated into the DNA of dividing cells.  EdU is used to assay DNA synthesis in cell culture and to detect cells which have undergone DNA synthesis in embryonic, neonatal and adult animals . Whilst at high doses it can be cytotoxic, this molecule is now widely used to track proliferating cells in multiple biological systems. EdU-labelled cells may be isolated to determine the transcript of cells, from neural cancer or tissue that have undergone division in vitro and in vivo.
