Graft linker immobilization for spatial control of antibody immobilization inside fused microchips
2009 (English)In: Proceedings of Conference, MicroTAS 2009 - The 13th International Conference on Miniaturized Systems for Chemistry and Life Sciences, Chemical and Biological Microsystems Society , 2009, 1566-1568 p.Conference paper (Refereed)
A new method for antibody immobilization to the inside of fused silica microchips coated with a protein repelling polymer (2-methacryloyloxyethyl phosphorylcholine polymer, MPC polymer) is described. Antibody patterning is achieved by using a new photoreactive linker which is composed of three-parts: a carboxyl group (-COOH), a hydrophilic PEG spacer and a photoreactive benzophenone. The linker is grafted with UV which introduces free carboxyl groups to the microchannel surface. Antibodies are immobilized to these areas, by using amide bonding between protein -NH2's and linker's -COOH. Patterned anti-BSA antibodies retained functionality and were capable of antigen specific capture.
