Fig. 2From: The cathepsin S cysteine proteinase of the burrowing nematode Radopholus similis is essential for the reproduction and invasionSouthern blot analysis of Rs-cps in Radopholus similis. Lanes 1–2, gDNA from R. similis digested with NdeI and EcoRI; lanes 3–4, gDNA from carrot callus digested with NdeI and EcoRI. The digested genomic DNA was hybridized with a 438-bp DIG-labeled probeBack to article page
