Poly-L-lysine hydrobromide (MW 70,000–150,000)（Cat No.:I042954）is a cationic polymer made from lysine, an amino acid. It is commonly used in biological and biomedical research due to its ability to interact with negatively charged surfaces, such as cell membranes, DNA, and proteins. This property makes poly-L-lysine hydrobromide useful in applications like gene delivery, tissue culture, and drug delivery systems. Its high molecular weight version enhances its binding capacity and stability, making it valuable in developing coatings for biomaterials or for improving transfection efficiency in gene therapy and cell culture experiments.
