FIG. 3.
Agarose (0.8%) gel (left) and corresponding Southern blots (right) of AR1, T4 ATCC 11303B4, and LG1 NdeI-digested genomic DNA. Whole-genomic, digoxigenin-labeled, NdeI-digested AR1 DNA was used as the probe for the Southern analysis. Lanes 1, lambda HindIII molecular size markers (2.0 to 23.0 kb); lanes 2, NdeI-digested AR1 genomic DNA; lanes 3, NdeI-digested T4 ATCC 11303B4 genomic DNA; lanes 4, NdeI-digested LG1 genomic DNA.
