Abstract
Several methods for immobilizing anti-T2 mycotoxin monoclonal antibodies on quartz fibers, for use in optical sensor development, have been evaluated with respect to the surface density and stability of the immobilized proteins. the first method activates matrix hydroxyl groups using p-toluenesulfonyl chloride (TSC). the second method activates these groups using p-nitrophenyl chloroformate (NPCF). the third method requires an initial silanization using 3-aminopropyltriethoxysilane (APTES) followed by carrier activation with glutaraldehyde. the activated carrier in all three methods is then reacted with the amino groups of the protein. the first two non-silanizing coupling methods are simple, inexpensive and non-hazardous compared to the third, more complex method in which an initial Correspondance: to PVS
