Zastosowanie

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

Działania biochem./fizjol.

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.

Komponenty

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.

Przestroga

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

Poli-lizyna zwiększa wiązanie komórek z dodatnio naładowanymi jonami powierzchniowymi, optymalizując interakcje elektrostatyczne na powierzchniach hodowli w celu zwiększenia przyczepności komórek.

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.

Białka macierzy zewnątrzkomórkowej, takie jak laminina, kolagen i fibronektyna, mogą być stosowane jako podłoża do mocowania komórek w hodowli komórkowej.
