Vector laboratories just sent a flyer on using a tomato lectin conjugated 
to rhodamine for staining blood vessels in tissues.  Go to 
www.vectorlabs.com and read their latest VECTAGRAM.

For further and specific methods, go to American Journal of Pathology, 
166(3), 2005 for a publication on using this method.  It can be done by 
intravascular perfusion or on tissue sections.  The publication used a FITC 
labeled tomato lectin and was quite elegant.
