Poly-L-Ornithine Hydrobromide
Solution, 0.1 mg/ml
Catalog #5058
Poly-L-Ornithine comes with 50 mL of a 0.1 mg/ml sterile-filtered solution. Poly-L-Ornithine is a synthetic amino acid chain that is positively charged and used as a coating to enhance cell attachment and adhesion to both plasticware and glass surfaces. This product’s molecular weight ranges from 70,000 to 150,000 Da.
Product Description
Poly-L-Ornithine is a synthetic amino acid chain that is positively charged having one hydrobromide per unit of ornithine. Poly-L-Ornithine is widely used as a coating to enhance cell attachment and adhesion to both plasticware and glass surfaces.
The molecular weight of Poly-L-Ornithine can vary significantly with lower molecular weight (30,000 Da) being less viscous and higher molecular weight (>300,000 Da) having more binding sites per molecule. This product’s molecular weight ranges from 70,000 to 150,000 Da yielding a solution viscosity for easy handling while providing sufficient binding sites for cell attachment.
Poly-L-Ornithine surface coatings are designed to improve cell attachment, growth and differentiation of many cell types.
Coated surfaces will often improve cell attachment in reduced or serum-free conditions. This product is supplied in a sterile 50 ml package size at a concentration of 0.1 mg/ml.

Use these recommendations as guidelines to determine the optimal coating conditions for your culture system. To maintain sterility, perform all operations in a laminar flow hood.
- A typical working concentration is 0.1 mg/ml. If a different concentration is desired, transfer desired volume of solution from the bottle to a dilution vessel. Dilute to desired concentration using tissue culture grade water or PBS.
- Add appropriate amount of diluted material to culture surface. Typically, 1 mL per 25 cm2 is used. Rock gently to ensure uniform coating of culture surface.
- After 5 minutes, remove excess solution by aspiration.
- Thoroughly rinse surface with tissue culture grade water.
- Incubate and allow to dry at room temperature or 37°C, covered, for at least 2 hours.
- Introduce medium and cells to the culture surface.
- Store remaining Poly-L-Ornithine at 2 to 10°C.
