Rehydration of DNA

To clarify matters, we are eluting the DNA from glass fibre mats and
not from silica particles; we are also using BSA in the PCR. The
amount of DNA bound and eluted is in the region of 100fg. From what
little I have found on the topic, DNA does rehydrate after drying - I
was curious as to the nature of the physics/chemistry of the process,
particularly release of anhydrous DNA from glass/silica/diatomaceous
earth. From our observations we concluded that DNA if not properly
rehydrated will not  PCR. It would be nice to have some facts to
support (or disprove) the hypothesis.
