ABSTRACT:
Process for preparing a vehicle substance capable of covalent bonding with iological material, especially enzymes, by reacting a matrix containing --OH or NH.sub.2 groups with an organic diisocyanate under anhydrous conditions. The distance between the matrix and biological material may be extended by a stepwise reaction of the matrix with an organic diisocyanate, and organic spacer containing two or more --OH and/or NH.sub.2 groups and again with an organic diisocyanate. The coupling of the vehicle material with biological material takes place in buffered aqueous solution.
