Yes, lectins are stable although trypsin enzyme digestion at 37C may be 
better than citrate buffer retrieval.  Also, there are buffer 
considerations for staining, i.e. TRIS Lectin buffer with Mg and Ca 
added.  The book gives the recipe for this and with some lectins PBS should=20
be avoided and also normal serums.

AND there is an excellent book on Lectin Histochemistry , a concise 
practical handbook SA Brooks et al, ISBN#1859961002  that gives IHC 
staining methods, etc.  It is not expensive and Springer Verlag is the 
publisher source.
