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.

Introduction
TFM Tissue Freezing Medium is an advanced formulation that is designed to support tissue during cryotomy.
It freezes tissue quickly without promoting crystallization even at the most extreme temperatures. TFM enables precise cutting with support for cryo-sectioning at 3 microns.Available in 5 different colors, TFM Tissue Freezing Medium enables histo-technologists to use color to easily
differentiate between multiple sections.Features and Benefits
Freezes Quickly
This unique and robust formula freezes quickly; supporting tissue for cryo-seȝ the matrix at temperatures from -8°C to -25°C.No Crystallization
TFM will not crystallize at extreme temperatures, meaning fewer ice artifacts to contend with.Less Curling
The enhanced formula means there will be less curling. Sections will flow freely under an anti-roll device, allowing flat
sections and easier pick-up from the knife edge.Reduced Water Content Minimizes Freeze Fracture
The reduced water content eliminates freezing chatter and does not cause autofluorescence. Color Variety Makes Differentiating Multiple Specimens EasyColor makes differentiating multiple specimens easy during sectioning and staining. Most histo-technologists currently
use clear, but now there are 5 colors to make differentiating between multiple specimens easier. Easily Removed During Fixation & Staining Procedures Without ResidueTFM can be washed away during fixation and easily rinsed prior to staining stages. It will not leave color residue.
Drying or fixing the slides in the cryostat for specific procedures will not affect the quality of the freezing medium.

TMD's formulations deliver consistent and durable pigments that permanently mark tissue throughout tissue processing. With TMD, tissue marking is now a one-step process - there is no need for a separate mordant/fixative as TMD includes fixative in the dye formulation itself. TMD dries quickly and allows precise and reliable definition of tissue marginsOrdering information
