Figure 4. Arginine peptide-improved transportation of DNA around and into the nucleus in live cells.

Figure 4

The cells were treated with FITC-labeled arginine peptide/rhodamine-labeled DNA complexes and imaged using confocal microscopy. (A) Rhodamine-labeled DNA (red); (B) FITC-labeled arginine peptide (green); (C) differential interference contrast; and (D) a merge of A, B, and C. Panel D illustrates the nucleus circled and the presence of both peptide-bound DNA and free DNA.
