This product is supplied as a 0.01% w/v solution.
The lower molecular weight poly-L-lysine (30-70 kDa) is easier to use because it is less viscous in solution, but the higher molecular weight poly-L-lysine (>300 kDa) provides more attachment sites per molecule. The mid-range product has a molecular weight range of 70-150 kDa.
Certain cells secrete proteases, which can digest poly-L-lysine. For those cell types, poly-D-lysine should be used.
For coating slides with poly-L-lysine, in general, it is recommended to use a 0.01% (w/v) solution. After a 5 minute incubation, the excess solution is removed and the slides are dried at room temperature or in an oven at gentle heat.
A solution of 0.1 mg/mL is prepared; 0.5 mL of that solution is aseptically transferred to a non-tissue culture treated 25 square cm flask. The flask is gently rocked to evenly coat the surface. After five minutes, the excess solution is removed and the surface is thoroughly rinsed with sterile water and allowed to dry for several hours.
Poly-L-Lysine coated slides can be exposed to UV light overnight for sterilization.
For coating slides with poly-L-lysine, in general, it is recommended to use a 0.01% (w/v) solution. However, if your protocol requires a more dilute solution, you can add sterile water or sterile buffer like Phosphate Buffered Saline.

Poly-Lysine enhances electrostatic interaction between negatively-charged ions of the cell membrane and positively-charged surface ions of attachment factors on the culture surface. When adsorbed to the culture surface, it increases the number of positively-charged sites available for cell binding.

Cancer stem cell media, spheroid plates and cancer stem cell markers to culture and characterize CSC populations.
Extracellular matrix proteins such as laminin, collagen, and fibronectin can be used as cell attachment substrates in cell culture.
Polyamino acids facilitate the attachment of cells and proteins to solid surfaces in biological applications. In cell cultures normal attachment, growth, and development of many cell types are dependent on attachment factors and extracellular matrix components.
