Researchers show that superpositively charged GFP enters mammalian cells with ease and can be used as a nucleic acid delivery vehicle. It's a bird, it's a plane, it's ... supercharged GFP!

Figure 1: GFP-fragment reassembly vectors and cloning linker sequences. To prepare the cloning vectors, transform separately pET11a-link-NGFP and pMRBAD-link-CGFP into an E. coli strain that gives ...
