Table 2. Formulations and Luciferase Expression of Mice Treated with Polyplexes via Hydrodynamic Injections^a.

sample	formulation	dose pDNA (μg)	luminescence 24 h (photons/s)	luminescence 48 h (photons/s)
Glycofect	N/P: 3	10	2.50 × 109*	1.39 × 109*
jetPEI	N/P: 7	10	3.70 × 107*	8.52 × 107*
jetPEI	N/P: 3	25	4.53 × 108*	1.64 × 108*
pMAT-b-AEMA-2	N/P: 3	10	4.39 × 1010	2.29 × 1010
pDNA	N/A	10	3.95 × 1010	8.93 × 109

^aLuminescence levels were averaged from the values obtained from 3 mice in each data set and are reported in photons/s. The logarithm of each measurement was calculated and samples that were found to be statistically different from pMAT-b-AEMA-2 were marked with an * (according to Student’s t-test with p < 0.05).
