Paraffin-embedded sections of the production method which is the most commonly used method of slices. As an organization filled with paraffin supported media, will be making entire organization-embedded tissue sections, 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, such as Carnoy fixative pathological tissue slices from ethanol, chloroform, acetic acid dubbed, faster and stronger force fixed tissue sections, without water, to avoid water-soluble substances such as glycogen and other losses in the fixed process. Precipitation tissue fixation, to remove tissue and infiltration of the fixative fixative produced, crystallization, pigments and other substances, otherwise it will affect the future of dyeing effect, the procedure shall be fixed after treatment. Processing method according to the fixative is selected, after paraformaldehyde fixed tissues commonly used to deal with running water for 24 hours (before running water, tissue blocks can appropriately trimmed, embedded and sliced ??to facilitate the production). In addition, Hebei tissue sections, calcium organizations, such as: bone, teeth, etc., should be carried out after rinsing decalcification. General use of calcium EDTA decalcification utterly organization, this method of tissue without damage, decalcification slow activity retention, less damage to tissue antigens.
