Abstract: A method is provided for detecting multiple analytes via their interactions with reagents. The analytes are immobilized on an analyte support and are divided into subdivisions by a blotting apparatus. Reagents are applied, each to a specific subdivision of the analyte support and binds to the analytes there.

Abstract: Arrays and methods for detecting one or more biological molecules, where the methods generally comprise the steps of: providing a first support immobilized with one or more reagents; providing a second support immobilized with one or more of ligands; contacting the reagents immobilized to the first support with the ligands immobilized on the second support whereby one or more of the reagents bind to one or more of the ligands; and separating the first support from the second support so that one or more of the bound reagents remain bound to one or more ligands on the second support after separation. In one preferred method, proteins are immobilized on a support with adequate strength so that the proteins can be dissociated from the support under certain conditions, such as after binding with other proteins immobilized on another support.
