Constitutive GFP Reporter
this is constituive active GFP reporter plasmid with intense GFP expression im mamalian cells.
-- All templates were received from AG Weber, BIOSS. The different parts of this device were amplified by PCR with primer with overlaps and via a four-fragment Gibson assembly ligated together.

Usage and Biology
-- This reporter plasmid can be used for several purposes. To assess transfection efficiency in mammalian cells the plasmid can simply be co-transfected. About 20h after transfection very bright green fluorescence shows what percentage of cells has taken up plasmids. This GFP repoter plasmid can further be used to show a repressive effect of gene-expression repression systems. Team Freiburg used it to show decrease of fluorescence intensity when the CMV promoter is targeted by Cas9 fused to KRAB which is responsible for repression. Last but not least the plasmid can also be used for gfp expression in prokaryotic cells. -- Sequence and Features
