Detection of Rifampicin and Isoniazid Resistance Mutations on Sanity 2.0 System

Product Detail

The MDR-TB Test Kit (Sanity 2.0) (Abbreviation: Sanity MDR-TB) is a cartridge-based test kit for detecting
multidrug-resistance mutations (including rifampin-resistant mutations and isoniazid-resistant mutations) in Mycobacterium tuberculosis (MTB) from sputum samples. This kit is designed to run on Sanity 2.0, which integrates nucleic acid extraction, real-time polymerase chain reaction (rt-PCR) and the result interpretation into a fully automatic instrument (all-in-one machine).




The Sanity MDR-TB employs dually labeled probes to target the excess single-stranded amplicons generated by asymmetric PCR; then uses melting curve analysis to generate the minus derivative of the fluorescence intensity versus temperature, and compares the melting temperature (Tm) to gain mutation information of the sequences. Where, perfect match of target sequence and probe gives the highest Tm; partially mismatch, e.g., point mutation, insertion or deletion, would cause decreased Tm than that of perfect match. The decreased degree is related to the type of point mutation, base number of insertion or deletion as well as the mutation location. Sanity MDR-TB covers the mutations of rpoB (codons 507~533) to determine the resistance of rifampin; the mutations of ahpC promoter region (positions -44~-30 and -15~4), inhA promoter
region (positions -17~-8), and katG codon 315, to determine the resistance of isoniazid.
