What species are you working with?  Mouse?  Human?

double stain antral and duodenal specimens for CD4 and CD25 & CD8 and CD25.
 Also, we would attempt to triple stain for TGF beta on these subsets.  We
have access to a Leica DMRXE although the filter cubes are all currently
long pass suppression filters . I have both formalin-fixed and frozen
sections of the antrum and the duodenum.

>1.	Can anyone share their experience on antibody combinations known to
work for CD4-25, CD8-25 and triple staining for CD4-CD25-TGFB either with
vectastain elite (peroxidase) or immunofluorescence.  I have compiled a
list of CD4, CD8, CD25, TGFB antibodies from Dako, Ancell, Novocastra, BD,
and Serotec, but before purchasing any of these, I thought it would be wise
to ask advise from the Histonet community.
>2.	I would probably need to acquire different filter cubes to do
simultaneous imaging of fluorescence.  There are several suppliers I have
encountered on the net (Omega Filters and Chroma Technology) * does anyone
have experience on using filters from these companies on Leica microscopes
(specifically the DMRXE).  Any problems encountered with using third-party
filters with Leica microscopes?
