       Do any of you have experience with the HOPE fixative  from DCS,
novative Diagnostik-Systeme from Hamburg, Germany?  One of our
researchers brought the article to show me and ask if we can use only
the HOPE I for frozen tissues and do OCT blocks, etc.  The HOPE II if
equal parts of the HOPE I and ice cold acetone to do dehydration
processing into low tem. paraffin for paraffin embedding.  HOPE is
Hepes-Glutamic Acid Buffer Mediated Organic Solvent Protection Effect.
It does not kill any bugs, etc. It does not completely denature
structural proteins, enzymes and nuclec acids.
