ENZYME PAPER FOR THE INDICATION OF CHOLINESTERASE- INHIBITORS, THE PREPARATION AND USE THEREOF

The invention relates to an enzyme paper, which is suitable for use in the detection of cholinesterase-inhibitors in a gas or liquid, a method of using the enzyme paper for such detection and, a method of making such a paper,which method involves an advantageous immobilization and stabilization of the enzyme on the paper. The enzyme paper consists of an enzyme carrier being a type of chromatography paper with ion exchange capacity and, having immobilized on the carrier, a cholinesterase enzyme, preferably from plaice, at least one component stabilizing the cholinesterase enzyme, preferably a carbohydrate, e.g. sucrose and dextran, and a surface-active substance, e.g. Tween 80*. *Trade mark ...
