Merck 109844 Eosin Y-solution 0.5% aqueous for microscopy



Katalog Numarası109844
AçıklamaEosin Y-solution 0.5% aqueous
Genel BakışEosin Y-solution 0.5% aqueous - for microscopy, is used for human-medical cell diagnosis and serves the histological and clinico-cytological investigation of sample material of human origin. The hematoxylin and eosin (H&E) staining method is the method most frequently used for the staining of histology material. This Eosin Y-solution is a 0.5% aqueous staining solution, that can be used e. g. for the histological staining of instantaneous sections.The staining mechanism behind the H&E staining is a physico-chemical process. In the first step, the positively charged nuclear dye (hematoxylin) Mayer’s hemalum solution for microscopy(Cat.no. 109249) or Hematoxylin solution modified acc. to Gill III (Cat. no. 105174) binds to the negatively charged phosphate groups of the nucleic acid of the cell nucleus. The nuclei will be dyed dark blue to dark violet. The second step is the counterstaining with negatively charged anionic Eosin Y, a xanthene dye. Eosin binds to the positively charged plasma proteins. Cytoplasm and intercellular substances are stained pink to red, while erythrocytes will appear with yellow to orange color.
The 500ml bottle provides 1500 stainings. It is an IVD registered product and CE certified, thus can be used for clinical diagnostic purposes. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
