Frozen formalin

From:Kim Carter

  I work in a research lab, so I get samples from many different sources. And they arrive in various ways. Today I received samples in 10% NBF. Then they placed the vials in dry ice before they mailed them. When I received these samples, both the tissue and the formalin was frozen.
  Has anyone gotten samples like this?  And how should I handle them? Will the H&E staining and the immunos be affected?
  I would appreciate any insight. Thanks
