100bp ladder L8 L7 L6 L5 L4 L3 L2 L1 1kb ladder ~3,000 600 S300 Figure 5-4. Product of ecoRI digest of purified plasmids containing liver inserts L1-L8 The DNA sequences obtained are detailed in Appendix A. The results of the BLASTn search (best five sequences for each insert) are summarized below (Table 5-3). Very good matches were obtained with the Tetraodon nigroviridis cDNA, as well as Pleuronectes yokohamnae UGT I B2, several Danio rerio sequences and Strongylocentrotus purpuratus (sea-urchin) UGT2B sequences. There was also a good similarity between the longer insert and the mammalian UGTIA sequences. Better matches were obtained with the longer cDNA insert obtained from the liver (95 sequences with score >50) than with the shorter insert from liver or intestine (9 sequences with score >50).
