Re: [Histonet] PGP 9.5
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.
