Submit the tissue in 30 sucrose in 1×PBS or frozen embed your tissue samples in OCT compound and submit the tissue to the core facility as your earliest convenience On the day of your frozen section appointment put the samples on dry-ice or in liquid nitrogen and bring it to our Core Facility

What is snap-freezing of tissue samples?

Snap-freezing of Tissue Samples Protocol Introduction Snap-freezing, or flash-freezing, is the process by which samples are lowered to temperatures below -70°C very rapidly using dry ice or liquid nitrogen. Snap-freezing achieves the same endpoint as slow rate-controlled freezing but at a much faster rate.

How do you freeze tissue for immunohistochemistry staining?

Principle: Snap-freezing in isopentane (2-Methylbutane) is a preferred method of freezing tissues for immunohistochemistry staining due to the superb preservation of tissue elements and the lack of ice crystal artifact. Gently blot excess liquid off of tissue. Fill an appropriate container with some liquid nitrogen (black bucket).

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.

How long should a sample be frozen after vascularization?

Ideally, specimens should be snap-frozen or placed in appropriate reagent within 5 minutes from loss of vascularization to prevent the DNA, RNA and protein from degradation and keep the best morphology. Transfer the frozen sample into a cold, labeled cryo-vial, with a screw-top lid.
