Product Introduction:

The principle of Feulgen Stain is that after DNA is hydrolyzed by mild weak acid (such as hydrochloric acid), the glycoside bond between purine base and deoxyribose is opened, and the phosphate bond between deoxyribose and phosphoric acid is broken, forming free aldehyde group at one end of deoxyribose. The aldehyde group combines with Schiff Reagent in situ to form a purplish red compound, which makes the part containing DNA in the cell purplish red.
After dyeing, wash the tablets with SO2 Solution to remove the excess non-specific pigment and diffuse dye.Make it more clear and clean.
