Bouin's fixative can be a good fixative for some IHC applications but I cannot agree that it is good for lectin studies.
I did some studies on lectin binding severl year ago and found that the best fixative to be alcohol and acetone. Alcohol acetic probably is OK too. 
An important point here however is that there is considerable variation depending on the tissue and also on the lectin that is used.

	Must be more to it then that.  Bouin's is made up with formaldehyde.
