Hi Peggy

we use mo-a-PGP 9.5, clone 13C4, Biomeda Cat Nr. V3231. Working conc. is 1.5 
ug Ig/ml (corresponding to 1:200), pretreatment HIER (microwave) citrate, on 
FFPE tissue, cut at 2-3 um. Working conc. will depend on visualization 
system used. In our lab we visualize with StrABC method (either with 
peroxidase - DAB or alkaline phosphatase - new fuchsin, depending on 
specificproject). Hope this helps.
