Quality Assessment of Mycobacterium tuberculosis Genotyping in a Large Laboratory Network
Figure 2. A) Computer-derived IS6110 restriction fragment length polymorphism patterns from eight laboratories for one isolate. Addition or omission of bands is demonstrated. B) Autoradiogram images demonstrating the addition of IS6110 band in restriction fragment length polymorphism pattern in one subpopulation of Mycobacterium tuberculosis isolates used in the quality assessment exercise.
