Description

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

La poly-L-lysine est un polymère d′acide aminé à charge positive, comportant environ un HBr par résidu de lysine. Le bromhydrate permet de former une poudre cristalline de poly-L-lysine soluble dans l′eau. Une petite quantité de produit peut se trouver dans des structures bêta, car le HBr interfère avec la formation de liaisons d′hydrogène entre les groupes aminés et les groupes carboxyliques ou les parties contenant des atomes N ou O.
