At least ten thousand Randomly Amplified Polymorphic DNA (RAPD) reactions are required to complete even a modest RAPD-based genetic mapping effort, while more ambitious mapping projects may eventually require hundreds of thousands of RAPD react ions. Most molecular genetics laboratories are not designed to handle this level of production, and efforts to scale up the production level of RAPD reactions in a research laboratory by orders of magnitude can be frustrating and time consuming. We describe a recently completed RAPD laboratory of our own design which is capable of completing more than three thousand RAPD reactions per day with minimal space requirements (about 500 square feet). The laboratory features a robotic pipettor, custom designed electrophoresis rigs, and a customized database management system. Future enhancements to the RAPD laboratory that are currently under development, including an automated video analysis system, are also briefly described.
