Product Introduction:
Hematoxylin Stain Solution, GillⅡ is a nuclear staining solution for histology and cytology. 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.
Gill Ⅱ is a kind of semi oxidized hematoxylin staining solution. The concentration of hematoxylin was 2 times of that of Hematoxylin Stain Solution, Gill Ⅰ. This reagent belongs to progressive staining, so it does not need hydrochloric acid ethanol differentiation after staining. It is especially suitable for cytological smear staining, about 3-5min. It can also be used for paraffin section staining. The staining time of paraffin section should be more than 15 min. There is less section staining for clinical diagnosis. The disadvantage of the dye solution is that the adhered gelatin or even the slide itself will be colored.
