Can you freeze Oct cells if submerged in liquid nitrogen?
Note: DO NOT freeze the tissue by submersing into the liquid nitrogen, it will cause the OCT blocks to crack which makes them very difficult or impossible to section. This happens because the outside tissue begins to freeze much more quickly than internal portion.
Why should tissues be frozen for histology?
Freezing tissues for histology: Tissues should be frozen as rapidly as possible to avoid ice crystals and to promote the formation of amorphous (vitreous) ice. Freezing tissues slowly allows the water molecules to line up during the transition and form crystals, which results in volume expansion with destruction of cell
What happens if a tissue is frozen?
Otherwise, these liquid will form ice crystal on the surface of tissue and prevent tissue attach to frozen embedding media (e.g. OCT compound) when the tissue is frozen embedded and cause a lot of difficulties during sectioning.
How do you use isopentane to freeze tissue?
Put the metal canister containing isopentane into the liquid nitrogen or dry ice EtOH slurry. Cover with lid and allow to equilibrate for 3 to 10 mins. If the isopentane boils when a piece of dry ice is dropped in, then it is not yet cold enough for freezing the tissue.
