          DescriptionHEMATEIN (C.I. 75290) FOR MICROSCOPY
          OverviewHämatein (C.I. 75290) is a dye for the preparation of a color staining solution, for the specific staining of DNA in the nuclei. It is used in cytology and histology. Nuclei are stained blue, dark violet to black. Hematoxylins are mixed with trivalent positively charged metal salts and build up the so-called hematoxylin lakes, used for the selective staining of nuclei (DNA). The dye is a CE certified IVD product and has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible diagnostic staining.
