General description

Mayer′s hemalum solution - for microscopy, is used in hematoxylin-eosin staining (H&E), which is the most widely used histological staining technique. Nuclear staining is achieved using ready-to-use staining solutions, such as Mayer′s hemalum solution or Hematoxylin solution modified according to Gil III (Product number 1.05174). These solutions do not need to be filtrated prior use and the dye is oxidized in a controlled manner, which renders the results robust and allows a brilliant differentiation of the stained structures. Counterstaining of i.e. for proteins, collagen, keratin, intercellular substances. can be performed with Eosin Y solution 0.5 %, alcoholic (Product number 1.02439)or Eosin Y solution 0.5 % aqueous (Product number 1.09844).
The 500 ml bottle is sufficient for 1500 stainings. It is registered as IVD and CE certified product and can be used for clinical diagnostics. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.

A simple but reliable and safe anaesthetic procedure is required for surgical interventions in small rodents. Combined ketamine and xylazine injections are often used in rats for less invasive surgery, possibly with spontaneous breathing and without airway management. However, there
