Fig. 2From: Differentiation of Mycobacterium tuberculosis complex from non-tubercular mycobacteria by nested multiplex PCR targeting IS6110, MTP40 and 32kD alpha antigen encoding gene fragmentsAgarose gel electrophoresis of nested multiplex PCR for the identification of Mycobacterium tuberculosis complex from clinical samples. Lane-1: positive control (H37Rv); lane-2: clinical samples positive for IS6110 and MTP40; Lane-3- negative control (MQ water); Lane-4- negative clinical sample; lane-5- patient samples positive for only IS6110and negative for MTP40 Back to article page
