Poly(L-ornithine hydrochloride) Structure

Product Description:

Poly-L-ornithine hydrochloride is a positively charged synthetic polyamino acid having one HCl per ornithine unit. It is a crystalline solid soluble in water. Poly-L-ornithine hydrochloride is a good alternative to poly-L-ornithine hydrobromide in applications where biocompatibility is critical. Applications for poly-L-ornithine hydrochloride are similar to poly-L-lysine hydrochloride and include the conjugation to active molecules for improved activities, the layer-by-layer deposition techniques, and the complexation with nucleic acids for gene expression.
