产品描述： Poly-L-Lysine (PLL) is a synthetic, positively charged amino acid chain that enhances cell adhesion by

altering surface charges on the culture substrate [1]. It is commonly used as a coating agent to promote

cell adhesion in culture. In addition to promoting cell adhesion, PLL surface treatments improve the survival

of many primary cells in culture and support neurite outgrowth. This concentrated solution contains polymers

in the 70 - 150 kDa range.
