Description:
Thiazolyl Blue Tetrazolium Blue (MTT) may be used in measurement of cell proliferation. MTT produces a yellowish solution that is converted to dark blue, water-insoluble MTT formazan by mitochondrial dehydrogenases of living cells. The blue crystals are solubilized with acidified isopropanol and the intensity is measured colorimetrically at 570 nm. MTT has been used as a histochemical/cytochemical reagent and for the detection of NAD. ADP-linked enzyme systems in tissue cannot be detected with MTT, due to binding of the cation by the cyanide trap used. MTT is rapidly reduced to the formazan, which chelates with nickel, copper, and cobalt; the cobalt chelate has been used in oxidative systems.

Description:
In hematoxylin-eosin staining (H&E), 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 Gill III. 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 alcoholic or aqueous Eosin Y solution 0.5 %. It is registered as IVD and CE certified product and can be used for clinical diagnostics.
