Serotec sells a CD52 antibody clone YTH34.5, which is a rather interesting
epitope on B (and some T) lymphocytes (hematologists/oncologists use a
anti-CD52-antibody for treatment). 

Unfortunately I could not get any results on FFPE tissue, trying a variety
of pretreatments including HIER in different solutions and
trypsin/chymotrypsin.

PS: The same theme was discussed in October 2001. I'm wondering if anybody
out there in histoland has been successful the last few months.
