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.
