Poly-L-ornithine hydrobromide (MW 30000-70000)  (Synonyms: L-Ornithine homopolymer hydrobromide (MW 30000-70000))

Poly-L-ornithine hydrobromide (MW 30000-70000) is a poly-lysine derivative with a molecular weight of 30000-70000. Poly-L-ornithine hydrobromide (MW 30000-70000) binds to the surface of cell culture vessels through positively charged amino acid residues to form a coating that promotes cell adhesion and provides cells with a matrix environment required for growth. Poly-L-ornithine hydrobromide (MW 30000-70000) is used as a coating agent in cell culture and can be used for the study of primary culture of neurons (such as dopaminergic neurons and oligodendrocytes)^[1][2].

Poly-L-ornithine hydrobromide (MW 30000-70000) (overnight) can be used as the first layer matrix for cell culture plates and the dual coating method of polylysine - laminin, for culturing primary mouse midbrain dopamine neurons^[1].
Poly-L-ornithine hydrobromide (MW 30000-70000) (0.1 mg/mL) provides a stable and reliable adhesion surface for the differentiation study of neural stem cells^[2].
