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.
Useful in promoting cell adhesion to solid substrates
Disclaimer
