Production of protein microarrays. Schematic representation of the production of autofluorescent protein microarrays. A. For programmable arrays each element is comprised of monoclonal anti-GFP antibody and linear DNA encoding specific target proteins, robotically printed as multiple sub-arrays. B. GFP-tagged proteins are immobilized on array elements after transcription and translation using a cell-free transcription-translation system.
