Poly-ʟ-Ornithine

Research Category: Stem Cell Research

Research Sub Category: Adhesion (CAMs)

Poly-L-Ornithine Solution (0.01%) has been used to coat:

• glass-bottom plates for cell plating in a research study investigating the localization of cMET in MDA-MB-468 cells using confocal microscopy
• culture dishes for adult human neural stem cells (ahNSCs) primary culture
• 6-well plates for induced pluripotent stem cells (iPSCs) culture and neuronal differentiation

Solution is clear with no particulates present. Solution is sterile and suitable for cell culture applications.

Product is presented in sterile water at 0.01% w/v (0.1mg/ml). Product is filtered through a 0.2 micron filter before freezing.

1. Thaw Poly-L-Ornithine solution at room temperature.

2. Dilute Poly-L-Ornithine solution to the desired concentration in sterile water.

3. Fully coat the cell culture surface with diluted Poly-L-Ornithine solution. Use 5 mL volume for 6-cm plates and 10 mL volume for 10-cm plates and T75 flasks.

4. Allow the cell culture vessel to sit at room temperature overnight.

5. Aspirate the Poly-L-Ornithine solution the following day and rinse the vessel with sterile water followed by coating with desired ECM protein. Optimal coating concentrations must be determined by the end user. Typical coating concentrations range from 10ug/ml to 100ug/ml based on cell type and application.

Store at -20°C for up to 4 months from date of receipt. Avoid multiple freeze thaw cycles to maintain product integrity.
