Various sections of the following methods are basically making permanent slides of various slicing method. Before slicing the light of the material properties to make certain processed tissue sections, sliced, stained and will enter the stage of filmmaking. Unarmed slice: means only hands and blade to slice method. If the material is too small, can be placed through the dry grass in Kaifeng marrow tissue slices, then sliced ??by hand. Wood chips: Wood Xuchang tissue sections due to quality hard and difficult to slice, cut need to take appropriate size (typically 0.5 × 0.5 × 4 cm, adapted to the size of the slicer) to remove material boiling method of gas, then material is softened (the softening agent such as glycerin, triethylene glycol), then after the material softening microtome sectioning. Buried wax sections: the material buried in paraffin blocks, and then together with wax block with cut, sliced ??and then finished material in paraffin removal method. Paraffin-embedded sections of the production method which is the most commonly used method of slices. Paraffin as a filling supported media organizations, which will be embedded tissue block, and finally solidified into a uniform solid structure. With sliced ??very thin slices taken mechanism. In order to be able to make paraffin immersed within the organization, the need to organize after dehydration treatment. Process is as follows: ⑴ fixed: biological samples from the body or the training environment, the cells will occur autolysis, corruption decomposition. Therefore, need fixative treatment, the protein coagulation or postmortem changes to stop dying. Where specimens for permanent preservation are subject to a fixed handle. Commonly used fixative is formaldehyde, ethanol and the like, to make the protein coagulation. There are several reagents dubbed by fixative Jiaozuo tissue sections, such as Carnoy fixative, by ethanol, chloroform, acetic acid dubbed fixing force faster and stronger, without water, to avoid water-soluble substances such as sugar original and other losses in the fixed process.
