Application

Poly-D-lysine polymers can be used in preparing surfaces for cell attachment. The D-lysine polymers can also be used with cells that digest

poly-L-lysine polymers and cause an excessive uptake of L-lysine.

This product is recommended as a cell culture substratum when using 0.5 - 1.0 mL of a 0.1 mg/mL solution to coat 25 cm2. Lower molecular

weight versions of the product are less viscous, but high more molecular weight versions provide more attachment sites per molecule.

Biochem/physiol Actions This product is a nonspecific attachment factor for cells useful in promoting cell adhesion to solid substrates by enhancing electrostatic interaction

between negatively charged ions of the cell membrane and the culture surface. After absorption to the culture surface, poly-D-lysine increases the

number of positively charged cell binding sites.

Caution 无菌溶液可在2-8℃条件下稳定保存2年。脱水保存在-20°C条件下。
