Question

For Histotechnologists: How do you dispose paraffin tissue blocks?

Answer 1

Tissue sections (5-7 µm thick) are cut from paraffin-embedded blocks on a microtome and mounted from warm water (40°C) onto adhesive microscope slides. Sections are allowed to dry overnight at room temperature or 40°C. CAUTION: ANTIGENS MAY BE DESTROYED BY EXPOSURE TO HIGH TEMPERATURES. (Adhesion of the section to the slide is essential to prevent tissue loss during subsequent incubations and washes).Deparaffinize and rehydrate tissue sections using standard methods. It is necessary to completely remove the embedding material. The xylene and alcohol bath solutions should be replaced frequently.http://www.chemicon.com/TechSupp/Protoco...
