To make the technique work in cultured mammalian cells, researchers must deliver small interfering RNAs (siRNAs), which are dsRNAs of 21-25 nucleotides, to the cell. They can use a wide range of ...

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!
