Poly-lysine is a polycation which binds to DNA, red cell membrane and any negatively charged protein. Molecular weight has been determined by Viscosity as well as by HPLC. It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction…

Poly-lysine is a polycation which binds to DNA, red cell membrane and any negatively charged protein. When adsorbed to the culture surface, poly-lysine increases the number of positively charged sites available for cell binding. A compromise between the easier to use lower molecular weight products…
