Table 1.

The polyplexes were prepared by mixing PCI-Luc plasmids (2 μg) with the above polymers (8 μg) in Opti-MEM for 30 min

Polymer	Polyplex size (nm)
H3K4b	490.3 ± 180.5
H3K4bt	654.3 ± 204.2
H2K4b	869.9 ± 341.1
H2K4bT	760.9 ± 92.4

The polyplexes were then diluted in Opti-MEM and the size of polyplexes was measured on N4 plus Submicron Particle Sizer.
