Açıklama | Eosin Y-solution 0.5% alcoholic |
Genel Bakış | The Eosin Y-solution 0.5%, alcoholic - for microscopy, is a ready-to-use solution that can be used for routine staining in the hematoxylin-eosin staining process (H&E) of sample material of human origin. The H&E staining process is the most frequently used staining method for histological material. The staining mechanism behind the H&E staining is a physico-chemical process. In the first step, the positively charged nuclear dye (Mayer's hematoxylin , Cat.no.109249, or Hematoxylin solution modified acc. to Gil III, Cat.no. 105154) 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. Cytoplasma and intercellular substances are stained pink to red, while erythrocytes will appear with yellow to orange color. The 500 ml bottle is sufficient for approx. 750 specimens. This product is registered as IVD and CE marked. For more details, please see instructions for use (IFU).
