Re: IgG, IgM on FFPE tissue
|From:||Amos & Theresa <firstname.lastname@example.org>|
We do not use any pretreatments on these antibodies. We use LSAB+ for
detection, and run them at 1:4000 for IgG, and 1:2000 for IgM. There are
occasional endogenous background issues, but the signal is usually strong
enough to be seen through the "noise". Alternatively one could use Envision to
eliminate this problem, usually the dilution is a little more concentrated
