AP18 Poly-L-Lysine (0.1 mg/ml) 5 mg £75.00

Description

Poly-L-Lysine is a synthetic amino acid chain that is positively charged having one hydrobromide per unit of Lysine. 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 yielding a solution viscosity for easy handling while providing sufficient binding sites for cell attachment.

Applications

Poly-L-Lysine enhances cell binding to polystyrene surfaces for certain cell-based assays and procedures.

Instructions for Use

Note: 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. 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.

1. 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.

2. After 5 minutes, remove excess solution by aspiration.

3. Thoroughly rinse surface with tissue culture grade water.

4. Incubate and allow to dry at room temperature or 37°C, covered, for at least 2 hours.

5. Introduce medium and cells to the culture surface.

6. Store remaining Poly-L-Lysine at 2 to 10°C.
