Cas no 26982-21-8 (poly-l-ornithine hydrochloride)
Poly-L-ornithine hydrochloride is a synthetic cationic polymer derived from the amino acid ornithine, commonly used as a coating substrate to enhance cell adhesion in vitro. Its positively charged structure promotes electrostatic interactions with negatively charged cell membranes, improving attachment for sensitive cell types, such as neurons and primary cultures. The hydrochloride form ensures solubility in aqueous solutions, facilitating consistent preparation. This polymer is valued for its biocompatibility and ability to support cell proliferation without inducing excessive stress. It is often employed in neurobiology, tissue engineering, and stem cell research, where stable cell-surface interactions are critical. Sterile filtration and standardized molecular weight options further ensure reproducibility in experimental applications.
