Lieferant:  SIGMA ALDRICH MICROSCOPY
Hersteller-Artikelnummer:: 318906-500ML
Lokale Artikelnummer:: SIAM318906-500ML
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.
VE:  1 * 500 mL

Beschreibung:   Phenolphthalein is an acid base indicator. It is a weak acid, which is colorless in acidic solution and turns puce pink in alkaline solution. Phenolphthalein is genotoxic. It might cause oxidative damage and binds to estrogen receptors. Phenolphthalein solution is a synthetic indicator. It is colorless in acidic and neutral conditions. Phenolphthalein gives pink color when added to a base, therefore it is considered as a base indicator.

Beschreibung:   Gram’s safranin solution, also known as Safranin T or Basic Red 2, is a ready-to-use staining solution that comprises 10% safranin in ethanol. Safranin is a basic, cationic, azine dye containing a planar, diaminophenazine chromophore, with a phenyl substituent attached to a ring nitrogen. The trimethyl cationic form of safranine is lipophilic, whereas the dimethyl forms are weakly hydrophilic. It is most notably used in bacteriology as a counterstain in Gram staining to differentiate between Gram-positive and Gram-negative bacteria.

Beschreibung:   Eosin Y is a xanthene dye and is used for the differential staining of connective tissue and cytoplasm. In histopathology, it is applied as a counterstain after hematoxylin and before methylene blue. It is also used as a background stain, thereby giving contrast to the nuclear stains.
