General description

Poly-L-ornithine is a positively charged synthetic amino acid polymer.


Poly-L-ornithine has been used successfully for the attachement and study of neural cell differentiation and outgrowth. Recommended as a cell culture substratum when using 0.5 ml of a 0.1 mg/ml solution to coat 25 cm2.
Poly-L-ornithine solution has been used in the induction of differentiation.

Biochem/physiol Actions

Poly-L-ornithine helps to improve the penetration of substances into cells. It can induce the uptake of DNA.

Preparation Note

Prepared in cell culture grade water.

Poly-lysine | Poly-D-Lysine | Poly-L-Lysine

Poly-Lysine enhances electrostatic interaction between negatively-charged ions of the cell membrane and positively-charged surface ions of attachment factors on the culture surface. When adsorbed to the culture surface, it increases the number of positively-charged sites available for cell binding.
