Poly-L-Lysine Solution (0.01%)

Poly-L-Lysine is a synthetic amino acid chain that is positively charged having one hydrobromide per unit of Lysine. Poly-L-Lysine is widely used as a coating to enhance cell attachment and adhesion to both plasticware and glass surfaces, improve growth and differentiation of many cell types. Certain cell types secrete proteases, which can digest Poly-L-Lysine. For those cell types, Poly-D-Lysine should be used. The molecular weight of Poly-L-Lysine for cell culture can vary significantly, from lower molecular weight of 30,000 Da being less viscous to higher molecular weight >300,000 Da having more binding sites per molecule. This product uses a Poly-L-Lysine of 84000 Da, yielding a solution viscosity for easy handling while providing sufficient binding sites for cell attachment.
