Poly-L-lysine (hydrobromide) (MW ＞300000)

Poly-L-lysine hydrobromide (MW 150000-300000), a positively charged amino acid polymer, is a nonspecific attachment factor for cells. Poly-L-lysine hydrobromide (MW 150000-300000) has good biocompatibility. Poly-L-lysine hydrobromide (MW 150000-300000) is used to increase cell adhesion to solid substrates by enhancing electrostatic interaction between negatively charged ions of the cell membrane and the culture surface[1].
