Analysis Note

Molecular weight based on viscosity. Also assayed by MALLS.

Application

Poly-L-ornithine hydrobromide has been used to coat coverslips in culture vessels for culturing neural progenitor cells. It has also been used to coat culture plates for culturing cerebral cells of mice.

Biochem/physiol Actions

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