Poly-L-Ornithine coating

Neuvitro Corporation owns the leading technology to provide professional coating with the broadest coverage of substrates, such as PDL, PLL, PLO, Collagen, Gelatin, Laminin, Fibronectin, PDL+Laminin, PDL + Fibronectin, PLO+Laminin, PLO+Fibronectin, PDL+Laminin+Fibronectin, etc. The majority of coated German coverslips available from Electron Microscopy Science, ThermoFisher Scientific, and VWR is actually manufactured by Neuvitro Corporation.

Poly-L-Ornithine is a synthetic amino acid chain that is positively charged and is widely used as a coating substrate to enhance cell attachment and adhesion to both plastic ware and glass surfaces. Poly-L-Ornithine is often used in combination with laminin for many types of neuronal and neural stem cell cultures. Poly-L-ornithine (PLO) has been used successfully for the attachment and study of neural cell differentiation and outgrowth.

Three groups of Poly-L-ornithine coatings are founded to be the most completed supplies:

1. Poly-L-Ornithine + Laminin coating for neuronal growth and differentiation,

2. Poly-L-ornithine + Fibronectin coating for neuron culture, and

3. Poly-L-Ornithine coated German coverslips for cell culture

Collection of poly l ornithine coating protocols:

Poly l ornithine coating protocol from CSH

Prepare 1.5-mg/mL (100X) aliquots of poly-L-ornithine hydrochloride by diluting in H2O. Store at −20°C.
2. Prepare coated plates:
- To coat 6-well plates for biochemistry:
- i. Dilute the 100X poly-L-ornithine to 1X in sterile 1X PBS, and pipette enough of the solution to cover the surface of each well. Incubate plates overnight at 37°C.
- ii. The next day, aspirate the coating solution and wash three times with H2O, making sure the H2O thoroughly fills each well. Air dry in a tissue culture hood until no H2O remains.
- iii. Store covered in foil at 4°C if the plate is not to be used immediately.
- To coat 24-well plates for morphology assays:
- iv. Sterilize a packet of 12-mm coverslips by rinsing for several hours in 70% ethanol and drying overnight under the UV light of the tissue culture hood.
- v. Place one coverslip in each well of the 24-well plate, add 0.5 mL of 1X poly-L-ornithine coating solution (diluted as in Step 2.i) per well, and follow the incubation/rinsing procedure described in Step 2.ii, using at least 1 mL of H2O per well.

Poly l ornithine (PLO) coating protocol from Sigma

Optimal coating concentrations must be determined by end user. Typical coating concentrations range from 10ug/ml to 100ug/ml based on cell type and application.

1. Thaw Poly-L-Ornithine solution at room temperature.
2. Dilute Poly-L-Ornithine solution to 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 cell culture vessel to sit at room temperature overnight.
5. Aspirate the Poly-L-Ornithine solution the following day and rinse vessel with sterile water followed by coating with desired ECM protein.

Poly l ornithine coating protocol from 101bio

Dilute poly-l-ornithine (Cat.#: P3655, Sigma) on ice using sterile tissue culture-grade water(20μg/mL). Aliquot the diluted poly-l-ornithin and keep the aliquots in -80°C until use.
Aliquot laminin (Cat. #:L2020, Sigma) on ice and keep the aliquots in -80°C until use.
Coat 6-well plate withpoly-l-ornithine (20μg/mL) 1 mL / well, and incubate at 37°C for 2hours.
Aspirate poly-l-ornithine and rinse the well twice with 1 mL of DPBS.
Add 1 mL of lamininsolution (5μg/mL) in the well and incubate at 37°C for 2 hours.
Aspirate the laminin before plating cells or store plate at 4°C until needed.

Poly l ornithine coating protocol from Trevigen

The recommended working concentration is 0.1 mg/mL (as provided),but optimal conditions for attachment must be determined for each cell line and application.
Slides may be dipped in the solution and air dried before applying sample. Keep sterile.A.
