Description_x000D_ Application_x000D_ 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._x000D_ Packaging_x000D_ 10 mg in glass bottle_x000D_ 50, 100, 500 mg in poly bottle_x000D_ Biochem/physiol Actions_x000D_ 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._x000D_ Analysis Note_x000D_ Molecular weight based on viscosity._x000D_ Other Notes_x000D_ For additional technical information on polyamino acids please visit the Polyamino acid FAQ resource.
