MeltPro® MTB/STR Test Kit
MeltPro® Mycobacterium tuberculosis Streptomycin-resistance Mutation Test Kit
Mycobacterium tuberculosis Streptomycin-resistance Mutation Test is suitable for rapid, qualitative de-
tection of streptomycin-resistance mutations in Mycobacterium tuberculosis.
Mycobacterium tuberculosis Streptomycin-resistance Mutation Test is based on the Probe-based Melting
Curve Analysis. According to the change in Tm value between targets and the corresponding wild-type
probe sequences, the test detects mutations in rpsL codon 43 and codon 88, rrs positions 513~517 and
positions 905~908, which reports streptomycin-resistance information. For each specimen, two tubes are
needed for the test, corresponding to the STR PCR Mix A and Mix B.
Detection region: mutations in rpsL codon 43 and codon 88, rrs positions513~517 and positions 905~908
(mutation rate 70%~90%)
Principle of Probe-Based Melting Curve Analysis
Probe-based melting curve analysis is based on melting temperature generated by thermal denaturation of
the probe-target hybrid. Melting curve plot of fluorescence (F) versus temperature (T) is transformed into
melting peak by plotting -dF/dT versus temperature. The hybridization probe with fully matched wild-type
target gives the highest Tm value. With matched mutant-type target, it gives the lower Tm value.
Mutation is detected as Tm deviation (△Tm ) compared to the wild-type hybrid.
Intended Use: CFDA approved in China for clinical use, CE marked for IVD use in Europe.
