A. Paraffin paraffin method include technical subjects, fixed, washed and dehydrated, transparent, dipping wax, embedding, sectioning and sticky films, dewaxing, staining, dehydration, transparent, were mounted and other steps. General organization drawn from fixed to glass slides were mounted into biological specimens slice take several days, but can be stored for a long specimen used for permanent microscopic slide specimens. General steps we all know, is not to say, the value of say a few caveats 1. Fixed organization must, under the premise of convenience as a small point, depending on the tissue fixative to choose the right source. Fixative is generally used in an amount of about 20 times the mass of material of biological slice manufacturers, is a fixed time according to the size and mass of material bulk density and degree of penetration rate of fixative may be, can be from 1 hour to several days, usually for a few hours to 24 hours. Pure alcohol can be fixed glycogen and can dissolve fat, formaldehyde can be fixed general organization, but dissolved glycogen and pigments; single cell can not be fixed in fixative all ingredients; mix fixative can complement biological slice suppliers, often mixed fixed There was Bouin's solution, Zenker's solution, FAA solution, Carnoy's solution, SuSa liquid II. paraffin technical advantages and disadvantages of paraffin (paraffin section) histological methods in conventional production techniques most widely used. Paraffin sections were observed not only for normal tissue morphology, but also the pathology and forensic medicine and other disciplines to study, observe and form the main method to determine changes in cells and tissues, but also has been quite widely used to study many other disciplines in. Teaching, light microscopy biopsy specimens mostly paraffin sections were prepared. In immunohistochemistry on this one. Frozen section procedure is simple, less antigenic activity is lost during production, but the organization is poor cell morphology; many steps paraffin sections of biological specimens, the producers of the antigenic activity has reduced, but the clear tissue morphology, chemical preparation routine immunohistochemistry One slice method. Paraffin-embedded tissue sections generally used to detect cytoplasmic or nuclear antigen within, not so surface antigen staining.
