Poly-L-lysine hydrobromide (MW 70000-150000)

Poly-L-lysine (hydrobromide) (MW 70000-150000) is a positively charged amino acid polymer serving as a non-specific cell adhesion factor. It exhibits excellent biocompatibility and enhances cell adhesion to solid substrates by increasing electrostatic interactions between the negatively charged cell membrane and the surface of the medium.
