METHOD FOR REAL-TIME DETECTION OF BEIJING GENOTYPE MYCOBACTERIUM TUBERCULOSIS Russian patent published in 2014 - IPC C12Q1/68 

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to medicine and microbiology. What is presented is a method for real-time detection of Beijing genotype mycobacterium tuberculosis by detecting IS6110 element insertion in a locus of dnaA-dnaN genome differing by the fact that real-time PCR is carried out with the use of two specific primers 5`-AGATCAGAGAGTCTCCGGACTCA and 5`-CGCCGGGACTGTATGAGTCT and fluorescence-labelled probe R6G-5`-TGTGCACAGCGACACTCACAGCCA-3`-BHQ2; the result is assessed by recording a fluorescence signal in R6G canal at wavelength 555nm; if a sample contains the DNA of the Beijing genotype mycobacterium tuberculosis strain, an exponential growth of the PCR fluorescence signal when a pure DNA analysed is observed between 10 to 15 cycles, and when cell lysates analysed - between 15 and 20 cycles.

EFFECT: invention can be used for laboratory detection of Beijing genotype mycobacterium tuberculosis.
