text: DGGE was invented by Leonard Lerman, while he was a professor at SUNY Albany.
  The same equipment can be used for analysis of protein, which was first done by Thomas E. Creighton of the MRC Laboratory of Molecular Biology, Cambridge, England. Similar looking patterns are produced by proteins and nucleic acids, but the fundamental principles are quite different.
  TGGE was first described by Thatcher and Hodson  and by Roger Wartell of Georgia Tech. Extensive work was done by the group of Riesner in Germany. Commercial equipment for DGGE is available from Bio-Rad, INGENY and CBS Scientific; a system for TGGE is available from Biometra.
