First 4 primers 1 2 3 4 All the contigs walked hundreds’ bps toward the gaps. 453F3’s 2600 reads 12 contigs Overlapping BAC-454F24’s 200 reads + Sp6 T7 1 3 2 4 a b c Second 3 primers 1200bp’s AT-rich , (CATATATA)n repeat. Finally, filled by using ET sequencing Kit . 1240bp’s GC-rich, GC-content is 69.03% ; the BAC’s is 39.98%. We used dGTP Kit filling it. Sp6 T7 Completed sequence ?
