Abstract
A novel class of cross-linking agent, which comprises a monomeric organic compound having at least two hydroxyl groups each bonded to a different carbon atom, wherein said hydroxyl groups are activated by reaction with 2-fluoro-1-methylpyridinium toluene-4-sulfonate (FMP). Suitable monomeric organic compounds include diols and polyols. Such cross-linking agents may be conveniently prepared by reaction of the monomeric organic compound with FMP in a suitable solvent, followed by recovery of the resultant reaction products, e.g., via precipitation and filtration. The novel cross-linking agents have a wide variety of uses, including the interconnection of subunits of multimeric enzymes and the covalent immobilization of organic ligands to suitable carriers or supports.
