Poly-L-lysine hydrobromide (MW 150000-300000)(CAS: 25988-63-0)

Poly-L-lysine hydrobromide (CAS: 25988-63-0) is a water-soluble polypeptide derived from the L-lysine amino acid. It is characterized by its high molecular weight (150,000-300,000 Da) and is commonly used in research for attaching cells to surfaces in tissue culture. The molecular formula is (C6H11NO2)n·HBr, where n is the number of lysine units, and it contains hydrobromic acid groups.

Poly-L-lysine hydrobromide (CAS: 25988-63-0) is primarily used in the field of cell biology and neuroscience for adhering cells to surfaces in tissue culture. It is also used in drug delivery systems, as a stabilizer in biopharmaceuticals, and for immobilizing proteins and other biomolecules on surfaces for research purposes.

Poly-L-lysine hydrobromide is generally considered safe for its intended applications, but handling should be done with protective gloves and goggles to avoid skin and eye contact. It is not toxic to cells in the concentrations typically used, but dilution and careful handling are recommended. Storage and disposal should follow standard laboratory safety protocols.

Poly-L-lysine hydrobromide should be stored in a cool, dark, and dry place at temperatures between 2-8°C. Avoid exposure to light and high humidity, which can degrade the product. Store the compound in a tightly sealed container to prevent moisture absorption. Ensure the container is labeled clearly and kept out of reach of children and unauthorized personnel.
