    melanin black. The nucleus will stain pink/red. The cytoplasm will stain light pink.

    Gabe Trichrome

    A trichrome histology stain is a mixture of three dyes. This histology stain can be

    helpful for differentiating cellular from extracellular items.

    Giemsa Stain

    This is a histology stain for peripheral blood smears and bone marrow. It is also

    used to visualize parasites and malaria. This is a Romanowsky type stain.

    Methylene blue and eosin are used. Erythrocytes stain pink/red. Platelets andleukocytes stain blue. This micrograph depicts the appearance of a well-stained

    slide using the Giemsa staining technique. Note that the acidic components of the

    cellular constituents such as the cytoplasm and chromatin, pick up the basic

    methylene blue azure compliments of the Giemsa stain, which reveals the

    characteristic blue coloration of this stain.

    Golgi Stain

    This histology stain will stain neurons.

    Gomori Trichrome

    A trichrome histology stain is a mixture of three dyes. Gomori's trichrome will

    stain connective tissue and collagen green or blue. It stains muscle, keratin and

    Hematoxylin & Eosin

    This is a standard histology stain. "H&E" stand for hematoxylin and eosin.

    Hematoxylin and eosin stain is used for routine tissue preparation frequently. This

    is the most often used combination in the histology lab for general purpose

    staining. With an H&E stain, mucus and cartilage will stain a light blue color.

    Hematoxylin can be thought of as a basic dye. It binds to acidic structures,

    staining them blue to purple. It will bind and stain nucleic acids. Therefore, the

    nucleus stains blue.

    Eosin is an acid aniline dye. It will bind to and stain basic structures (or negatively

    charged structures), such as cationic amino groups on proteins. It stains them

    pink. Cytoplasm, muscle, connective tissue, colloid, red blood cells and decalcified

    bone matrix all stain pink to pink/orange/red with eosin.

    Iron Hematoxylin

    This histology stain will stain nuclei bluish/black.

    Luna Stain

    fibers and mast cells will stain purple. Nuclei will stain black.

    Luxol Fast Blue

    This histology stain is the alcohol soluble equivalent of alician blue. Luxol fast blue

    is used to demonstrate myelin. It stains myelin blue to blue/green. Neurons stainviolet. Red blood cells stain blue.

    Mallory Trichome

    A trichrome histology stain is a mixture of three dyes. This histology stain is used

    on connective tissue to visualize collagen and reticular fibers.

    Masson Trichome

    A trichrome histology stain is a mixture of three dyes. This histology stain can be

    helpful for differentiating cellular from extracellular items. This histology stain

    uses light green, iron hematoxylin, and acid fuchsin. It is useful on connective

    tissue.

    Collagen fibers stain green or blue with Masson's trichrome stain. Muscle and

    keratin will be red. Cytoplasm will be pink to red. Nuclei will be black.

    Movat's Pentachrome Stain

    This histology stain is used to visualize connective tissue.

    Mucicarmine

    Mucicarmine is a histology stain used to see epithelial mucin. It stains it a deep

    red.

    Nissl Stains

    These histology stains are basic dyes. They stain RNA and DNA. It is used to see

    Nissl body in neurons. Nissl bodies stain purple/blue.

    Nuclear Fast Red

    This histology stains nuclei red. The cytoplasm will be unstained or yellow. This

    histology slide of the liver tissue stained postive for calcium deposits (stained

    black) with Von Kossa and the background is stained with nuclear fast red.

    Oil Red O

    This is a histology stain used for lipids. Lipids will stain red. Nuclei will stain

    blue/black.

    Orcein Stain

    A histology stain used for elastin fibers.

    Osmium Tetroxide

    This histology stain can be used to stain lipids. Collagen and erythrocytes will stain

    brown. Myelin and lipids will stain black.

    Papanicolaou Stain

    This histology stain is used mainly on exfoliated cytological specimens. Cells in

    smear preparations can be stained with Pap staining. Gynecological smears (Pap

    smears), sputum, urine, cerebrospinal fluid, abdominal fluid, pleural fluid,

    synovial fluid, semminal fluid and fine needle aspiration samples can all be

    stained with a Pap stain. This staining technique involving five dyes in three

    solutions.

    Periodic Acid-Schiff (PAS)

    This histology stain is particularly useful for staining glycogen and other

    carbohydrates, but is useful for many things. It is often used to show glomeruli,

    basement membranes, and glycogen in the liver. PAS stains glycogen, mucin,mucoprotein, and glycoproteins magenta. The nuclei will stain blue. Collagen will

    stain pink.

    Phosphotungstic Acid-Hematoxylin (PTAH)

    This histology stain is used to stain striated muscle fibers and mitochondria. They

    will stain blue. Nucleus, red blood cells and muscle all will stain blue. Collagen will

    stain red. In this histology slide of the tongue, PTAH stains the collagen pink, fibrin

    blue, and striated muscle blue as well.

    PicroSirius Red (polarized)

    When used with polarized light, this is a way to visualize collagen. With polarizedmicroscopy, collagen fibers will be bright yellow or orange and the thinner fibers

    will be green.

    Prussian Blue

    stain. These histology stains are based on a combination of eosin and methylene

    blue.

    Safranin O

    This histology stain will stain mucin, cartilage and mast cells. It stains them

    orange/red. Safranin O is sometimes used as a counterstain.

    Silver Stain

    The silver salts will be seen in argyrphilic tissues. Silver histology stains are used

    to show melanin and retiuclar fibers. Reticular fibers will stain black.

    Van Gieson

    This histology stain is sometimes used in conjunction with iron hematoxylin. This

    histology stain can be used to differentiate collagen and smooth muscle.

    Cytoplasm and muscle stains brown/yellow. Collagen stains red. Red blood cells

    stain yellow. Cartilage stains pink.

    Verhoeff Stain

    A histology stain used for connective tissue and particularly to see elastic fibers.

    Sometimes a counter stain is used. This histology stain is can be useful when

    looking at lung tissue and arteries. Elastin will stain a dark brown/black. The

    nucleus of cells stains black.

    Von Kossa Stain

    This histology stain is a silver reduction method used to visualize calcium and

    calcium deposits. Here the chondrocytes in the growth plate are staining black.

    Wright's Stain

    This histology stain is used for blood smears and bone marrow smears.

    This histology stain uses a blend of basic dyes, such as methylene blue derivatives

    and acid dyes, such as eosin.

    Red blood cells stain reddish/pink. Eosinophilic granules will be a bright

    orange/red. The nucleus of white blood cells will stain purple. Basophilic granules

    will stain blue/black. Neutrophilic granules stain pale brown. Platelets stain

    purple. The cytoplasm of lymphocytes stains pale blue.

    This histology slide has been stained using an "automatic staining" device. It is a

    Wright's stain. The acidic components, such as the nucleic acids, will take on the

    basic portion of the stain, or the methylene azure color, and stain blue. The basic

    components, such as erythrocyte hemoglobin, will stain pink with eosin, since

    eoisn is an acidic dye.
