Poly-L-lysine Hydrochloride（Cat No.:I044341）is a synthetic, positively charged polymer composed of L-lysine residues, widely used to enhance cell adhesion in tissue culture and biomedical applications. By coating surfaces such as glass or plastic, it promotes attachment and spreading of a variety of cell types, including neurons and epithelial cells. The hydrochloride form improves solubility and handling. Poly-L-lysine also facilitates transfection, drug delivery, and surface modification in biosensor and biomaterial development. Its electrostatic interaction with negatively charged surfaces and molecules makes it a versatile tool in cell biology and bioengineering research.
