Lys-Lys-Lys-Lys Chemical Properties,Uses,Production
Uses
Tetralysine is a cationic moietie that may be used in the construction of gene delivery vectors and DNA nanoparticles[1].
Biological Activity
Short poly-L-lysines polypeptides such as trilysine (lys3), tetralysine (tetra-L-lysine, lys4) and pentalysine (penta-L-lysine, lys5) are cationic moieties th at may be used in the construction of gene delivery vectors and DNA nanoparticles.
