Transgene expression in NIH/3T3 cells mediated by immobilized complexes to HA-collagen-NA substrates. % biotinylated PEI indicate the percent biotinylation of the complexes. The symbols * and ** represents a statistically significant level of p<0.05 and <0.01; respectively, for single comparisons between biotinylated complexes and non-biotinylated complexes. Complexes were formed at an N/P ratio of 5. Plotted data is an average of triplicate conditions ± SD.
