Frozen sectioning frozen section method is to use the tissue at low temperatures to freeze hard to achieve compliance with the requirements of sections. The need for frozen sectioning cryostat, or in the general section with refrigeration facilities. Cryostat is a senior cryosections equipment. It has a cryostat tissue sections, refrigeration units and slicer specimens are housed in the box. Similar effect cryostat refrigerator, the temperature can be adjusted within a certain range, its structure is conducive to maintaining a constant low temperature chamber, to reduce interference when the ambient temperature of the door opening. Rotary slicer handle mounted on the outside box Henan tissue sections offer easy to manipulate slices. Advantages of frozen section method is: was handled, it can maximize their fresh state organization. And, because without dehydration, transparent, wax dip during the treatment of organic solvents, and the impact of wet hot wax dipped boxes Henan tissue slice processing, even without immobilized. So well preserved organize various ingredients and enzyme activity of the cells, and therefore used this method in chemical research slice of tissue enzymes. The following briefly describes several aspects from the principle of common staining technique: a display of succinate dehydrogenase (SDH) activity nitro -BT law: (Succinate dehydrogenase) ⑴ positioning enzymes and biological significance: succinic off mitochondrial marker enzyme catalase Henan tissue sections suppliers, which are present in all cells of aerobic respiration, and mitochondrial closely. Without coenzyme and enzyme itself has flavoprotein (FP, Flavoprotein) supplemented groups. In the group of reaction is often used to reflect the situation in the citric acid cycle. ⑵ Principle: The final step of the above reaction principle, nitro -BT (Nitro-blue tetrozolyum, tetrazolium) systems can vary tetrazolium ring compounds, when it accepts the hydrogen itself is reduced to a colored precipitate the product ( A) (Formazan).
