 Use of Poly-L-lysine hydrochloride


Poly-L-lysine hydrochloride is a nonspecific attachment factor for cells useful in promoting cell adhesion to solid substrates by enhancing electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. Poly-L-lysine is a strong-attraction regulator that promotes liquid-liquid phase separation (LLPS) at low concentrations but suppresses LLPS at high concentrations. Antibacterial cationic peptide.[1].

In Vitro Poly-L-lysine is a food-grade antimicrobial peptide that forms complexes with proteins. Such complexes are potential carriers for targeted delivery of agents. Electrostatic potential modelling of EPL was employed to describe the interaction affinity. A three-dimensional phase boundary curve was established which divided the complexation into a nano-scale and phase separation[2].
