Figure 6. Southern blot analysis of genomic DNA. Genomic DNA was isolated from first instar larvae and digested with restriction enzymes EcoRI (E) or BamHI (B). The blot was hybridized to the SSGP-11A1 cDNA (panel A). After the blot was stripped or decayed, the blot was rehybridized sequentially to probes specific to SSGP-11B1 (panel B) and SSGP-11C2 (panel C). DNA size markers were indicated on the left of the figure.
