Hi Kelly If the tubes that hold your frozen ab aliquots do not have a complete seal....the water in them will lyophilise, over time.
I have your problem occasionally, for that reason ( I have a couple of thousand frozen primary abs) Use snap-lid tubes ( I use 200microL PCR tubes) Hope that explains.
