Embedding: embedding refers to the organization after the package Baptist wax process is a piece with embedding medium (paraffin, collodion, resins, etc.). Tissue bag method most commonly used is paraffin embedding, made of wax blocks. Slice: Slice refers slicer paraffin tissue blocks depending on the thickness of the sheet and cut into tissue test requirements. Slide base to prevent off-chip, so that tissue sections firmly attached to the top of the slide. Commonly used rendering method is polylysine backing. Test equipment and test reagents: 1. Equipment: surgical instruments, laboratory animals, jars, fixative, label sheet 2, fixed: formaldehyde fixative fixative: 1 part liquid +9 parts of formaldehyde in water to form a ratio of 4% formaldehyde, or 10% formalin. 4% neutral formalin configuration: 40% formaldehyde 100ml, filling pig specimens manufacturers, distilled water 900ml, Hebei specimen manufacturers, sodium dihydrogen phosphate (NaH2PO4 H20?) 4g, disodium hydrogen phosphate (anhydrous) 13g, the pH value 7.0 Ethanol fixative: for a fixed concentration of generally 80% -95%. 3, dehydration: Leica dehydrator, 70%, 80%, 90%, 95% ethanol. 4. Transparency: xylene (benzene, toluene, chloroform, cyclohexanone, etc.) 5, the Baptist wax: Leica embedding machine, soft wax (melting point 54 ℃ or less), hard wax (melting point 60-62 ℃). 6. Slice: Leica slicing machines, disposable blades, poly-lysine, slides, weasel specimen manufacturers, water bath, oven. 2, dehydration: the removal of moisture within the organization, through some vehicle replacement process water within the organization. Usually after fixation of tissue often contain more water, and the water is not mixed with wax, therefore, must take off before Baptist wax organization blocks moisture. Ethanol is most commonly used dehydrating agent, can be freely mixed with water, strong drainage capacity, Oriole specimen manufacturers, and hardened tissue. Its penetrate tissue quickly, often leading to tissue block contraction, brittle. Thus, the use of ethanol dehydration, it should start with a low concentration Start, and then turn increasing concentrations of ethanol, using different concentrations of ethanol water gradually displace tissue within the block.
