Abstract: The present invention relates to a method for specifically detecting Mycobacterium tuberculosis and nontuberculous mycobacteria by simultaneously amplifying and analyzing target genes using various primers and probes, and a kit using same. The method of the present invention is capable of selectively detecting Mycobacterium tuberculosis and nontuberculous mycobacteria with very high efficiency through a multiplex real-time polymerase chain reaction (PCR) using probes and primers specific to target genes (particularly, IS6110, 16S rRNA and ?-actin). Also, the kit of the present invention is capable of conveniently and efficiently detecting the target genes in a sample through a multiplex real-time PCR. Therefore, the method and the kit of the present invention are capable of selectively detecting with ease whether or not there is an infection with Mycobacterium tuberculosis or nontuberculous mycobacteria in a sample, and can be more accurately applied to the treatment of diseases on the basis thereof.

Abstract: Improved methods for use in nucleic acid amplification, including multiplex amplification, where the amplification is carried out in two or more distinct phases are disclosed. The first phase amplification reaction preferably lacks one or more components required for exponential amplification. The lacking component is subsequently provided in a second, third or further phase(s) of amplification, resulting in a rapid exponential amplification reaction. The multiphase protocol results in faster and more sensitive detection and lower variability at low analyte concentrations. Compositions for carrying out the claimed methods are also disclosed.
