[Histonet] OCT embedded Tissue Storage

[Mathew DeGutes]

I have a couple questions.  In the lab I work in we have started to accumulate a number of
experiments worth of tissue blocks that we would like to keep for reference at later dates.
Generally tissue survives better while still embedded in a block than when in slide form, so I was
curious as to what sorts of methods others here employ to keep order and good preservation of
blocks in -80s?  Up until now we have been just keeping individual sets of blocks in Ziplock bags,
but it has gotten to be unwieldy.  I am looking for any suggestions of a good way to keep the
blocks well preserved and easily recovered in -80s.
