Ouch, it is not uncommon to freeze samples for a long time, especially rare ones like this. You're free to peruse the literature on how this is an accepted practice.

So I did. Searched and read about it, found out the viability and recovery of cryopreserved PBMC has a clear downward slope. Samples are good for years, not decades.

This depends on what you want to do. The DNA can certainly be sequenced. They might even be viable if you’re nice to them.

What I mean to say is this is an accepted practice in many labs, including ones I have worked in. In my experience, these were old tumor cells stored in LN2. Sources include: https://link.springer.com/article/10.1007/BF01131376
