A higher density of surface amines can be achieved with the Poly-L-Lysin which is covalently attached on 3D-surfaces. Slides covalently coated with Poly-L-Lysine can be used as adhesive microscope slides for the electrostatic coupling of biomolecules or biological samples, e.g. DNA, cells, tissues.
PolyAn equips glass slides and polymer slides with Poly-L-Lysin. Please do not hesitate to contact us, if you would like to functionalize a different format or substrate with our Poly-L-Lysin surface.
