Development of Au-Nanoprobes Combined with Loop-Mediated Isothermal Amplification for Detection of Isoniazid Resistance in Mycobacterium tuberculosis

Figure 10

Detection of MDR-TB members via Au-nanoprobe assay. (a) Agarose gel showed LAMP products. Lane 1 (M): Ladder DNA marker; Lanes 17–30: Mut as MDR-TB, Sus as INH susceptible, and Neg as negative. (b) Corresponding results recorded visually after salt challenge. Red colour showed the presence of the target, while purple indicated its absence.
