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, coverslips 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.
