Hardened reagent coatings, and processes for the preparation thereof.

摘要

The invention relates to hardened reagent coatings, and processes for the preparation thereof. The reagent coatings are used in so-called "dry-chemical" test agents, which are also known under the name test strips. The reagent coatings have a matrix, based on protein and/or polymer, which are hardened by carboxyl group-activating crosslinking agents, also named hardeners below. The reagent coatings according to the invention are so hard that they can be wiped withous suffering damage.
