γ-irradiated, BioReagent, for cell culture, mol wt ≥300,000, lyophilized powder
Biochemical and Physiological Mechanisms
Poly-D-lysine (PDL) hydrobromide 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

Product Description
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.
This compound belongs to the class of organic compounds known as d-alpha-amino acids. These are alpha amino acids which have the D-configuration of the alpha-carbon atom.
