Other Notes

A polycation which binds to DNA, red cell membrane and any negatively charged protein. For the preparation of polycationic beads, useful in immobilization techniques.; Immobilization of membranes; Immobilization of plant protoplasts; In cell culture, immobilization by microencapsulation with the alginate-poly- L-lysine microcapsule system; Drug-Polylysine conjugates: Their potential for chemotherapy and for the study of endocytosis
For additional technical information on polyamino acids please visit the Polyamino acid FAQ resource.
Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.

Disclaimer

Sterile solutions are stable for up to 2 years when stored at 2-8°C. It should be stored desiccated at -20°C.
