Abstract

The use of cationic biopolymer surfaces for high protein binding affinity matrices is described. As model proteins, fluorescently labeled bovine serum albumins (FITC-BSA, TRITC-BSA) have been employed. The amount of proteins on such cationically rendered surfaces was quantified by QCM-D. In addition, flexible, transparent, patterned COP slides have been prepared and loaded with proteins ranging from 15 pM to 15 μM TRITC-BSA.
