Re: [Histonet] Honey as a fixative?

From:Philip Oshel

I would be very surprised if there is anything in honey that acts as 
a fixative. Remember that honey is evolved to be food for growing bee 
larvae, not exactly something compatible with fixation.
I do find it easy to believe that honey acts as a preservative, 
simply because its high sugar content makes honey a strong 
dehydrating agent. This will perserve tissue and prevent bacterial 
and fungal growth. It would be interesting to do a similar study on 
salt-preserved tissues. I suspect the results would be similar, 
although the morphology would be uglier in the salt-preseved tissue 
because salt's strong osmotic effects.
