Opis ogólny

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.

Zastosowanie

Poly-L-lysine hydrobromide has been used to precoat glass bottom dishes used for in vitro cell culture.
Recommended as a cell culture substratum when using 0.5 ml of a 0.1 mg/ml solution to coat 25 cm2. Optimal conditions for attachment must be determined for each cell line and application.

Działania biochem./fizjol.

Poly-L-lysine serves as a pre-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.

Produkty

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.

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.
