HI,
Iam a Grad student at UMDNJ NJ USA..we have been trying to transfect human PBMC and follow the expression with egfp.The positive control was pmaxGFP supplied with the Amaxa transfection kit.we have tried different possibilities but no expression..
we have changed the promoter of our constructs to CMV and we have an IRES in the construct..
the size of the plasmid is about 9kb.
please suggest about transfection in human PBMC.
thanks,
BASKAR

Why don't you check the following website.

They have FuGENE 6 Transfection Reagent - Roche Applied Science, that might be of your interest.
Hope it helps
