Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Trypan Blue (C.l. 23850) is a large, tetrasulfonated anionic, hydrophilic dye. It is also known as diamine blue 3B. Trypan blue has been used as a dye in trypan blue exclusion assay/cell viability assay to detect dead cells.
Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Brilliant Blue R (C.l. 42660) is a triaminotriarylmethane dye with two amino groups being benzylated and one phenylated. It is also known as brilliant indocyanine 6B and coomassie blue R250. Brilliant Blue R has been widely used for protein band detection after SDS-PAGE (sodium dodecyl sulfate-polyacrylamide gel electrophoresis).

Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Auramine O, Sigma-Aldrich®
UOM:  1 * 25 g
Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Sulforhodamine B (also known as SRB, kiton rhodamine B, lissamine rhodamine B, or sulphorhodamine B) is a bright-pink anionic, aminoxanthene dye carrying two sulfonate substituents.
Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Basic fuchsin is a triaminotriphenylmethane dye that is widely used to stain muscle, mitochondria, and collagen. It is generally a mixture of pararosaniline (C.I. 42500), rosaniline (C.I. 42510), magenta II and new fuchsine (CI 42520).
UOM:  1 * 25 g
Numéro de catalogue: (O8639-4X500ML)

Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   For use with Osteo-bed bone embedding kit. Solvent for removal of plastic from sections prior to rehydration and staining. Most histochemical and immunohistochemistry staining protocols require the removal of methyl methacrylate (MMA) and rehydration of mounted sections for improved stain penetration and greater contrast.
UOM:  1 * 2.000 mL
Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   1-Amino-4-bromoanthraquinone-2-sulphonic acid sodium salt, Sigma-Aldrich®
UOM:  1 * 25 g
Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Acridine is a small cationic and planar dye that mainly binds to RNA and DNA. These dyes are strongly fluorescent. It resembles the structure of xanthene except that the heteroatom is nitrogen, not oxygen. Acridine is suitable for nucleic acid staining, particularly for cell cycle determination. Acridines are used as fluorescent materials for visualisation of biomolecules, and in laser technologies.

Description:   Metachromatic dye
UOM:  1 * 100 g
Numéro de catalogue: (60730-10G)

Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Khellin, for microscopy (4,9-Dimethoxy-7-methyl-5H-furo[3,2-g][1]benzopyran-5-one)
UOM:  1 * 10 g

Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Ehrlich’s reagent III, Loeffler’s Methylene Blue. Methylene Blue was earlier recognized as a good nuclear stain, the staining solutions are always either aged or alkalized, if not both. More importantly it is an excellent stain for ribonucleic acid, which is the important stainable constituent of bacterial bodies, of lymphocyte and hemoportoal cytoplasm, and of nerve cell tigroid granules. It can also be employed in capsule stain. The capsule stain begins as a negative stain leaving the organisms colorless. The capsule are clearly seen as halo surrounding the bacterial cell. Another staining procedure is performed with nigrosin (Cat. No. 43925).
UOM:  1 * 100 mL

Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   4'-Hydroxybiphenyl-4-carboxylic acid 99%, Sigma-Aldrich®
UOM:  1 * 5 g
Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Anthrone, also known as 9(10H)-Anthracenone, is a planar tricyclic aromatic ketone. In acidic conditions, anthrone reacts with carbohydrate to yield a blue-green colour.
Fournisseur:  SIGMA-ALDRICH MICROSCOPY
Description:   Sudan IV has been used to in en-face staining of aorta, stains the lipid rich plaques. It has also been used to stain lipids atherosclerotic lesions of mice.
