General description

Poly-L-ornithine is a positively charged synthetic amino acid polymer.[1]

Application

Poly-L-ornithine solution has been used in the induction of differentiation.[2]
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.

Biochem/physiol Actions

Poly-L-ornithine helps to improve the penetration of substances into cells.[3] It can induce the uptake of DNA.[4]

Preparation Note

Prepared in cell culture grade water.

Questions

1–2 of 2 Questions  
  1. CAt#P4957 do I just coat with the stock solution? at what conditions? RT or 37C or other? For how long?

    1 answer
    1. This product is a 0.01% or 100 ug/mL solution. The recommended surface coverage for this product is 4 μg/cm2. Provided the surface area of the vessel accommodates this concentration, the product may be used undiluted. A T-25 Tissue Culture flask has a surface area of 25 cm2.

      In this case. 1 mL of the undiluted product would be sufficient to coat the entire culture surface. Conversely, a 96 well flat bottom plate will have a culture area of approximately 0.150cm2 requiring approximately 0.6 ug to coat the surface. In this example, it may be more practical to dilute to a practical volume. Surfaces may be coated at room temperature. Incubate at least 5 minutes before removing excess solution. Coated vessels may be sterilized by UV and stored in a sealed container for up to 1 year. Avoid using coated vessels or slides that have any yellowing or changes in the surface appearance as this is an indication of degradation.

  2. Will poly-L-ornithine still be effective if it is incubated for 2 hours at 37°C, as done with other substrates, instead of being coated at room temperature overnight as indicated?

    1 answer
    1. The optimal coating conditions, including the required incubation time and temperature, are application-dependent and should be determined empirically. For reference, this product has been reported to coat well at 37°C with just 30 minutes of incubation time in a publication that may be of interest (Nature. 2019 Aug;572(7770):543-548. doi: 10.1038/s41586-019-1464-0. Epub 2019 Aug 7. Pol II phosphorylation regulates a switch between transcriptional and splicing condensates, PMID: 31391587).
