Product Description
Poly-L-Lysine is a synthetic amino acid chain that is positively charged and widely used as a coating to enhance cell attachment and adhesion to both plasticware and glass surfaces.
The molecular weight of Poly-L-Lysine 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.
Poly-L-Lysine is supplied in a 50 ml amber bottle containing 5 mg of Poly-L-Lysine. The product has been sterilized and is ready-to-use after proper addition of cell culture water.

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. To achieve a 0.1 mg/ml concentration, add 50 ml of tissue culture grade water or PBS to the 50 ml bottle. 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 cm2is used. Rock gently to ensure uniform coating of culture surface.
Option A:
- Allow to incubate for 60 minutes at room temperature, remove excess solution by aspiration.
- Thoroughly rinse surface with tissue culture grade water and aspirate rinse water.
- Incubate and allow to dry at room temperature or 37°C, covered, for at least 2 hours. Coated cultureware can be stored for up to 1 week. Go to Step 9
Option B:
- Allow to incubate overnight at room temperature, remove excess solution by aspiration.
- Thoroughly rinse surface with tissue culture grade water and aspirate rinse water.
- Incubate and allow to dry at room temperature or 37°C, covered, for at least 2 hours. Coated cultureware can be stored for up to 1 week.
- Introduce medium and cells to the culture surface.
Store remaining Poly-L-Lysine solution at -10 to 30°C
