I am collecting samples and embedding them in OCT for future cryosctioning and other studies. What is the best way to store and what is the maximum duration?
Once you embed the fresh tissue samples in OCT, you can store it at a temperature of -80 C for preservation over a long period of time. In my experience, the samples stayed preserved for 3 months. It can potentially be stored for a longer duration than that.
