Electrophoresis of PCR products on a 2% agarose gel (top panels and bottom right panel) or PCR product digest on a 3% agarose gel (bottom left panel). In each panel, lane M is the molecular weight marker. (Top left) Lanes 1 to 11 are DNA isolated from feces of control subjects. Lane 12 shows amplification of a 123-bp fragment from the positive-control DNA. (Bottom left) Digested PCR products, showing 66- and 57-bp fragments. Lanes 1 to 6, results from intestinal TB patients; lanes 7 and 8, results from pulmonary TB patients. Lane 9 is the positive control. (Top right) Lanes 1 to 11 show results from various intestinal TB patients, while lane 12 is a positive control. (Bottom right) Lanes 1 to 11 show results from patients with smear-positive pulmonary TB, while lane 12 shows the positive control.
