  • Thermodynamic Characterization of Polypeptide Complex Coacervation.: The research investigates the thermodynamic properties of polypeptide complex coacervation, including the role of Poly-L-ornithine hydrobromide in these interactions. This study provides insights into the self-assembly processes of polypeptides, which are crucial for designing new biomaterials (Priftis et al., 2012).

The impetus to develop non-viral gene delivery vectors has led to examination of synthetic polycationic polymers as plasmid DNA (pDNA) condensing agents. Previous reports have highlighted superiority (up to x 10-fold) in the in-vitro transfection of pDNA complexes formed by

Gene transfer vectors formed between the cationic polyamino acid, poly-(L)-omithine (PLO) and plasmid DNA (pDNA) have demonstrated superior transfection efficiency (up to x 10-fold) compared to equivalent polylysine-based systems in-vitro. The mechanism(s) underlying this observation remains to be elucidated. We
