    Construction of rv3852 knockout Mtb and verification by Southern blot and PCR. (A) Upper panel displays the genetic organization of the rv3852 region in Mtb (WT), Lower panel displays the same region with replacement of rv3852 by hygromycin resistance gene in rv3852 knockout Mtb (KO). Filled rectangle indicates the location of probe used in the Southern blot. Sites of digestion by BclI on genomic DNA from WT and KO as well as the sizes of the generated DNA fragment (a and b) are demonstrated under each panel. PCR products from genomic DNA from WT (1 and 2) and KO (3 and 4) are denoted. (B) Left, Southern blot of BclI digested genomic DNA from WT and KO. Calculated sizes of the fragments hybridizing with the probe were 3714 bp (WT) and 2916 bp (KO) as indicated in A. Right, PCR products from genomic DNA from WT and KO. The calculated sizes of the PCR products were 902 (Lane 1), 860 (Lane 2) for WT and 1322 (Lane 3), 1560 bp (Lane 4) for KO as indicated in A.
