Application
- pour enduire des plaques destinées à la culture de cellules précurseurs gliales de rat (RGPCS).
- pour enduire des fioles et des boîtes pour la culture de tanycytes.
- pour préparer la surface de lamelles couvre-objet et faciliter l'adhésion cellulaire.
Il est recommandé d'utiliser ce produit comme substrat de culture cellulaire, à raison de 0,5 à 1,0 ml de solution à 0,1 mg/ml pour 25 cm2. Les versions de faible poids moléculaire sont moins visqueuses, mais les versions de poids moléculaire plus élevé offrent davantage de points d'attache par molécule.

Do you have a protocol for coating cell cultureware or glass coverslips/slides with Product P6407, Poly-D-Lysine?
The protocol for coating surfaces with poly-D-lysine is the same as for poly-L-lysine. The optimal conditions must be determined for each cell line and application. In general, the following steps can be used.1. Add 50 ml of sterile tissue culture grade water to 5 mg of poly-D-lysine.2. Aseptically coat culture surface with 0.5-1.0 ml of solution per 25 cm2. Rock gently to ensure even coating of the culture surface.3. After 5 minutes, remove solution by aspiration and thoroughly rinse surface with sterile tissue culture grade water.4. Allow to dry at least two hours before introducing cells and medium.
Does Product P6407, Poly-D-lysine hydrobromide, need to be dialyzed to remove the hydrogen bromide?
The hydrogen bromide will not interfere with the cell growth. The hydrogen bromide salts are used to make our poly-L-lysine solutions that are cell culture tested. For these products, there is no interference in cell growth from the bromide.
Why would I use Product P6407, Poly-D-lysine hydrobromide, instead of poly-L-lysine?
Certain cells can digest poly-L-lysine, in which case the poly-D-lysine should be used.
How do I determine which molecular weight range of poly-lysine to use?
Poly-lysine is used to coat surfaces to increase the charge present. The lower molecular weight poly-L-lysine (30-70 kD) is easier to use because it is less viscous in solution, but the higher molecular weight poly-L-lysine (>300 kD) provides more attachment sites per molecule. The mid-range product has a molecular weight range of 70-150 kD. Please check the literature for information on the molecular weight range used for your cell type.
How should I store solutions of poly-lysine?
Poly-lysine solutions (0.1 to 1 mg/ml) can be sterile-filtered (0.2 um) and should be stored at 2-8 °C. Solutions should not be stored frozen as thawing can cause a decrease in the size (molecular weight range) of the polymer.
What protocol should I follow for coating Transwells with Product P6407, Poly-D-lysine dihydrochloride?
The same protocol can be followed for coating plates with poly-lysine. The transwell membrane is immersed in the poly-lysine solution.
How long can I store poly-lysine coated slides or plates?
Plates and/or slides can be stored after drying, protected from dust for up to 1 year. Inspect the plates/slides to make sure there are no cracks in the coating prior to use. Each lab should determine the maximum length of time for storage based on the application.
