Beschreibung: Eosin Y, also known as Eosin yellowish is a widely used xanthene dye. It is a counterstain that is used to distinguish between various connective tissue fibers and matrices, and the cytoplasm of different types of cells. Eosin in combination with hematoxylin is useful to demonstrate the general histological architecture of a tissue.

Beschreibung: o-Tolidine is a diacidic dye which is sparingly soluble in water and easily soluble in ether and alcohol. On exposure to chlorine or bromine vapors, it forms an intense blue color. This forms the basis for detection of chlorine, nitrates and hydrogen peroxide in air or water. It turns yellow on reacting with free chlorine. o-Tolidine easily forms acid salts.

Beschreibung: Formalin solution (10%, neutral buffered) is a widely used fixative for samples processed for light microscopy. It requires a relatively short period of fixation. It is suitable for the long-term storage of tissue. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining.

Beschreibung: Gram’s crystal violet solution, also known as gentian violet or hexamethyl pararosaniline, is a basic, cationic, acidotropic aminoarylmethane dye. It is a hexa-N-methylated triaminotriphenylmethane with a moderately sized lipophilic cation and a slightly nonplanar conjugated system. It is used in bacteriology as the primary stain in Gram staining to differentiate Gram-positive and Gram-negative bacteria. It is known to possess antibacterial and antifungal properties.

Beschreibung: 3,3′-Diaminobenzidine has been used as a chromogen for the visualisation in immunohistochemistry of chondrosarcoma sections, mammary carcinomas and brain tissue sections. Peroxidase substrate; reagent for spectrophotometric determination of selenium. DAB (3,3′-Diaminobenzidine) is utilized in many applications for the visualisation of peroxidase activity. In the peroxidase reaction, DAB serves as a hydrogen donor in the presence of peroxide. The oxidised DAB forms an insoluble brown end-product for use in the immunohistological and immunoblotting staining procedures.

Beschreibung: Phloroglucinol (phlo) is a phenol derivative that shows a cytoprotective effect from oxidative damage by enhancing the activity of cellular catalase. It can also be used to prepare synthetic analogs of A-type proanthocyanidins (PACs) such as 2,8-dioxabicyclo nonane derivatives by reacting with the corresponding flavylium salts. Phlo can react with benzaldehyde derivatives to form phloroglucinol-based microporous polymeric organic frameworks (phlo-POF) with potential applications in ion exchange and gas adsorption. Phloroglucinol is an antispasmodic and a derivative of phenol.
