Rapid arrayed filter production using the 'ORCA' robot

Abstract
By adapting a commercially available, general purpose laboratory robot, it is possible to produce high-density gridded hybridization filters of clone colonies or DNA products. We are using this system to produce 60–90,8 x 12 cm filters in an 8-hour day, each containing 3,456 clones arranged in 96, 6 x 6 grids.
