Description

Biochem/physiol Actions

Poly-L-lysine hydrobromide is used in the construction of biocompatible nanocapsules and for positively charged NH² group modification of bioactive surfaces in applications such as microarray and micropattern assembly.

Other Notes

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.
