Application

Poly-L-lysine hydrobromide has been used to coat:
  • 2-well plates before seeding muscle cells in a research study on rainbow trout myotube formation
  • flat bottom 96-well plates for in vitro neuronal stem cell differentiation
  • T75 flasks for primary astrocytic cultures

Biochem/physiol Actions

Poly-L-lysine serves as a coating substance to ensure better attachment of cells to culture surfaces. Research shows that plates coated with poly-L-lysine (PLL) demonstrated an accelerated cell growth rate. Culturing mesenchymal stem cells (MSCs) on PLL-coated substrates has been found to safeguard the stemness properties of these cells and inhibit senescence. PLL-coated plates have demonstrated enhanced MSC growth and up-regulated the expression of genes associated with cell adhesion, differentiation, proliferation, and signaling. Moreover, porous PLL-coated surfaces have shown improvements in cell proliferation and the osteogenic differentiation of MSCs.

Analysis Note

Molecular weight based on viscosity. Also assayed by MALLS.

Other Notes

For additional technical information on polyamino acids please visit the Polyamino acid FAQ resource.
Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.

Disclaimer

Sterile solutions are stable for up to 2 years when stored at 2-8°C. It should be stored desiccated at -20°C.
