I have been working with BDs FastImmune anti-IFNg and anti-IL-4 
antibodies for about 2 months (but only with normal controls) and have 
been very pleased with the results. I have been following BD's protocol 
and have had success with each experiment.  I have used both the 
IFNg/IL-4 combo with the isotype combo and individual reagents with 
success.  Although BD sells a special formulation of IgG1 PE, I have been 
titering their standard formulation and think it will work nearly as well 
as a control for IL-4 PE.  

I have not tried using saponin for permeablization but will be comparing 
BD's FACSPerm to Caltag's Fix N' Perm.

If you would like more details, please email me directly.
