Application
Short poly-L-lysines polypeptides such as trilysine (tri-L-lysine, lys3); tetralysine (tetra-L-lysine, lys4) and pentalysine (penta-L-lysine, lys5) are cationic moieties that may be used in the construction of gene delivery vectors and DNA nanoparticles.

Several injectable materials have been shown to preserve or improve cardiac function as well as prevent or slow left ventricular (LV) remodeling post-myocardial infarction (MI). However, it is unclear as to whether it is the structural support or the bioactivity

Formation of DNA-protein cross-links involving the initial formation of a guanine radical cation was investigated. For this purpose, riboflavin-mediated photosensitization of a TGT oligonucleotide in aerated aqueous solution in the presence of the KKK tripeptide was performed. We have shown

Polycationic polymers have been used to condense therapeutic DNA into submicron particles, offering protection from shear-induced or enzymatic degradation. However, the spontaneous nature of this self-assembly process gives rise to the formation of multimolecular aggregates, resulting in significant polyplex heterogeneity.

In order to develop a new gene delivery vector, a novel cationic poly(organophosphazene) was synthesized by stepwise nucleophilic substitutions of poly(dichlorophosphazene) with a hydrophilic methoxy-poly(ethylene glycol) (MPEG) as a shielding group and a branched tetra(L-lysine), LysLys(LysEt)(2), as a cationic moiety.

We studied the effectiveness of trilysine (Lys3), tetralysine (Lys4), pentalysine (Lys5), and poly-l-lysine (PLL) (MW 50000) on lambda-DNA nanoparticle formation and characterized the size, shape, and stability of nanoparticles. Light scattering experiments showed EC50 (lysine concentration at 50% DNA compaction)
