Application

Poly-L-ornithine hydrochloride has been used as a substrate analog of acetyl-poly-L-lysine to study substrate binding and catalysis of the NAD-dependent protein deacetylase Hst2. It has been used to bind alginate-polycation-alginate (APA) microcapsules.

Biochem/physiol Actions

Poly-L-ornithine is a polycationic synthetic amino acid polymer. It boosts nasal absorption of hydrophilic macromolecular drugs. Poly-L-ornithine is a specialized coating that acts as a charge modifier.

Analysis Note
