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 between negatively charged ions of the cell membrane and the culture surface. When adsorbed to the culture surface, poly-lysine increases the number of positively charged sites available for cell binding.Both the D- and L- form of the poly-lysine can be used as a coating substrate since poly-lysine is a nonspecific attachment factor for cells; however, certain cells can digest poly-lysine. In this case, poly-D-lysine should be used as the attachment factor so that the cells are not disrupted by excessive uptake of L-lysine.
