Here is a good summary article discussing this topic that I found if people want more reading.

This is classic academia. I didn’t realize how janky our entire academic lab infrastructure was until I moved into industry. When the freezer started alarming and couldn’t maintain temperature, the contents should have been moved right then. Instead, they decided to leave the freezer running not quite right and keeping juuuust cold enough for stuff to not thaw.

As a quick story, we had to replace our -80 freezer once when I was in grad school and we found samples frozen in the back of it that were literally older than my advisor that have been handed down over the years. These are tubes with cell lines preserved that, as far as I know, are the only preserved samples.

In fact, during grad school, I wanted to study a strain of bacteria that had a series of papers written about it back in the 70’s and 80’s. When I reached out to the authors, they told me that they lost those cultures due to equipment failure decades ago, and that is why they stopped publishing papers about it.
