Construction of long-range genomic maps by pulse field gel electrophoresis requires optimum resolution of large DNA fragments. Using the transverse-alternating field electrophoresis system, we describe a method to accurately evaluate the sizes of fragments generated by rare-cutter digestions within the 30-4700-kb range. A protocol generating large (greater than 1000 kb) molecules by partial digestion is also reported.
