WebMar 15, 2024 · In the progressive method, the tissue is initially stained with a hematoxylin solution that contains an excess of aluminum salts or acid, which increases nuclei affinity. 5 Washing with water follows before a counterstain is applied. Variation in color is due to the selective affinity of tissue components to hematoxylin. WebThe cryostat stubs used for our instrument can be seen at left below. Jam your frozen tissue quickly into the medium, and arrange in the best orientation for sectioning. Freeze the tissue onto the stub by plunging into liquid nitrogen or placing into the -20 ∘ C freezer.

Cryostats used in MRI machines are designed to hold a cryogen, typically helium, in a liquid state with minimal evaporation (boil-off). The liquid helium bath is designed to keep the superconducting magnet's bobbin of superconductive wire in its superconductive state. In this state, the wire has no electrical resistance and very large currents are maintained with low power input. To maintain sup… http://biotech.gsu.edu/core_facility/Documents/Manuals/HM-550.pdf
