Poly-D-Lysine Solution in PBS, 0.01%, Cell culture tested

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.
