Poly-L-lysine hydrobromide (C007B-565883)

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.Application: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.
