(D)Spoligotyping
統計: A(91), B(221), C(132), D(318), E(0) #671499
詳解 (共 2 筆)
Ribotyping : 為 RFLP 分析近一步的應用,偵測 rRNA 序列變異進行分型
PFGE : 改變電場方向使限制酶切割的大片段DNA分子有效分離
質體分析 : 限制酶剪切質體在進行電泳,也稱為質體限制酵素分析
Spoligotyping : 針對 direct repeat ( DR ) 區域之引子進行 PCR 增殖,將 PCR 產物和固定於薄膜上的 spacer sequence 進行雜交反應,有訊號的顯示為1,無訊號為0
The use of the polymerase chain reaction to identify pathogens, such as Mycobacterium tuberculosis, in laboratoryspecimens. It relies on the detection of unique spans of repeated DNA sequences found between the active genes of thepathogen. Culture-based methods of identifying mycobacteria are slow, often taking as long as 4 to 6 weeks to identifymicroorganisms in sputum or blood.
