METHOD FOR PREVENTING CHEMICAL CROSSTALK IN ENZYME-LINKED REACTIONS, AND ASSOCIATED ARRANGEMENT

摘要

The invention relates to a method for biochemical analysis using a micro-reaction array with at least two reaction chambers for materials which react together chemically or biochemically. According to the invention, the reaction chambers are smaller than 1 ~l, said reaction chambers are filled together by throughflow, the chemical or biochemical reactions of the substances retained therein then occurs in the individual isolated reaction chambers, thus preventing an interference between the reactions in the individual reaction chambers and the reaction products remain enclosed in the relevant reaction chambers. According to the invention, in said arrangement the planar array has at least two reaction chambers for substances, whereby means are provided for closing the reaction chambers with the goal of preventing an exchange of substances.
