Abstract: Array, and methods for the production thereof, of selected immobilized molecules for interaction analysis in which each molecule has a predetermined, identifiable position in the array. The array is obtainable by and the methods are characterized by the following steps: a) bundling and fixing together flat or elongated, thin carrier elements in a regular way, each element having immobilized thereto a selected molecule and having an identifiable position in the array, b) sectioning the bundles and optionally, c) depositing the sections on a support.
