Product Description

Poly-D-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.  This molecule is resistant to enzymatic degradation and has been used to culture a wide variety of cell types.

The molecular weight of Poly-D-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 yielding a solution viscosity for easy handling while providing sufficient binding sites for cell attachment.

Poly-D-Lysine surface coatings are designed to improve cell attachment, growth and differentiation of many cell types.  Coated surfaces will often improve cell attachment in reduced or serum-free conditions.  Poly-D-Lysine is supplied in a sterile 5 mg package size.

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.

  1. A typical working concentration is 0.1 mg/mL. 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.
  2. Add appropriate amount of diluted material to culture surface. Typically, 1 mL per 25 cm2 is used. Rock gently to ensure uniform coating of culture surface.
  3. After 5 minutes, remove excess solution by aspiration.
  4. Thoroughly rinse surface with tissue culture grade water.
  5. Incubate and allow to dry at room temperature or 37°C, covered, for at least 2 hours.
  6. Introduce medium and cells to the culture surface.
  7. Store remaining Poly-D-Lysine at 2 to 10°C.
