Arrays and methods for detecting one or more biological molecules, where the methods generally comprise the steps of: providing a first support structure fixed with one or more reagents; providing a second support structure fixed with a plurality of ligands; contacting the reagents fixed to the first support structure with the ligands fixed to the second support structure whereby a plurality of the reagents bind to one or more of the ligands; and separating the first support structure from the second support structure so that the plurality of the bound reagents remain bound to a plurality of 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. For example, antibody arrays produced according to the present invention may be used to detect protein expressions in a protein lysate and may be used in immunostaining to reveal the presence and location of protein in cells. |
