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].

Poly-L-lysine (hydrobromide) (MW ＞300000) is a cationic polyamino acid that can adsorb to the surface of the extracellular matrix or support particles, increases the positive charge sites on their surface, thereby improving the cell adhesion through electrostatic interactions^[2][3].
Poly-L-lysine (hydrobromide) (MW ＞300000) increases the density of cells within support particles, particularly for cells that cannot aggregate or adhere on their own, such as E. coli^[3].
Poly-L-lysine (hydrobromide) (MW ＞300000) can be used for cell culture to promote cell adhesion and growth^[2][3].
