title: Multiplex-terminal restriction fragment length polymorphism.
abstract: A novel method called "multiplex-terminal restriction fragment length polymorphism (M-TRFLP)" has been recently developed which can be used for simultaneous analysis of the community composition of two or more microbial taxa (up to four). This method can also be used for microbial diagnostic purposes. For M-TRFLP analysis, primers specific to different target genes are used for multiplex-PCR, with one primer for each target being labeled with a unique fluorescent dye at its 5' end. Restriction digestion of the amplified products followed by fragment size analysis on a DNA sequencer produces profiles for targeted genes, which can be distinguished from each other by the color of the terminal fragments imparted by the unique fluorescent dye used for primer labeling. In contrast to current protocols, M-TRFLP allows multiple communities or multiple targets (genes) data to be obtained in just one reaction and therefore saves time, cost and labor. This protocol can be completed in 5-8 h.
