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

Accumulating evidence suggests that iron homeostasis is disturbed in tumors. We aimed at clarifying the distribution of iron in renal cell carcinoma (RCC). Considering the pivotal role of macrophages for iron homeostasis and their association with poor clinical outcome, we

We recently reported that loss of hyaluronan (HA) from the endothelial glycocalyx leads to loss of vessel stability in specific microcirculatory vascular beds. Here we hypothesized that such derangements in the glycocalyx may also impair the adaptive response to vascular

Transient receptor potential melastatin 4 (TRPM4) is a Ca2+ -activated nonselective cationic channel that regulates cell migration and contractility. Increased TRPM4 expression has been related to pathologies, in which cytoskeletal rearrangement and cell migration are altered, such as metastatic cancer.
