Descripción

Descripción general

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.

Aplicación

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.

Acciones bioquímicas o fisiológicas

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.

Componentes

La poli-L-lisina es una polímero de aminoácido con carga positiva con aproximadamente un HBr por residuo de lisina. El hidrobromuro permite a la poli-L-lisina estar en una forma cristalina hidrosoluble. Puede encontrarse una pequeña cantidad del producto en la estructura beta porque el HBr interfiere en el enlace de hidrógeno entre el grupo amino y los grupos carboxilo o los grupos que contienen N u O.

Precaución

Las disoluciones estériles son estables durante un máximo de 2 años cuando se conservan entre 2 y 8°C. Deben guardarse desecadas a -20°C.
