Product Introduction:
Hematoxylin and Eosin combined staining is one of the most common staining methods in pathology and histology. Hematoxylin is an alkaline natural dye, which can stain the nucleus. The main component of chromatin in the nucleus is DNA. In the double helix structure of DNA, the phosphate groups on the two nucleotide chains are outward, making the outer side of the double helix of DNA negatively charged and acidic. It is easy to dye with positively charged hematoxylin basic dye by ion bond or hydrogen bond.
Carazzi's Hematoxylin Stain Solution is mainly composed of hematoxylin, aluminum potassium sulfate, etc. it belongs to a kind of alum hematoxylin liquid. The content of hematoxylin in the dye solution was little, and there was no oxide film. The staining of nucleus is very clear, without staining cytoplasm and fiber components. It belongs to progressive staining, so it does not need hydrochloric acid ethanol differentiation after staining.
