Pulsed-field Gel Electrophoresis via Contour-clamped Homogeneous Electric Field Gels Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4033

Category: Nucleic Acid Electrophoresis Protocols: Pulsed Field Gel Electrophoresis Protocols

Protocol for pulsed-field gel electrophoresis via contour-clamped homogeneous electric field gels. In CHEF gels, the electric field is generated from multiple electrodes, arranged in a square of hexagonal contour around the horizontal gel and clamped to predetermined potentials. Using a combination of low field strengths, low concentrations of aragose, long switching intervals, and extended periods of electrophoresis, DNAs up to 5000 kb can be resolved. - [Read Pulsed-field Gel Electrophoresis via Contour-clamped Homogeneous Electric Field Gels Protocol]
