Here, we provide methods for the creation of protein microarrays in microplates. The microplate consists of 96 wells with each well capable of holding a protein microarray at a spot density of up to 400 (20 × 20) individual elements. Arrays of capture monoclonal antibodies, corresponding to specific interleukins, were printed onto the bottom of the wells which had been surface activated for covalent attachment. A Biomek® 2000 laboratory automation workstation (Beckman Coulter, Inc., Fullerton, CA) equipped with a high-density replicating tool was used for printing low density 3 × 3 to 5 × 5 arrays. For higher density arrays, a microarrayer system (Cartesian PS7200, Genomic Solutions, Inc., Ann Arbor, MI) was employed. Multiple antigens were simultaneously analyzed without detectable cross-reactivity associated with capture antibody or secondary antibody interactions. Detection of interleukin antigens, spiked into cell culture media containing 10% fetal calf serum, was specific and sensitive.
