Schematic diagram of rNV96-908 capsid fragments expressed in E. coli. The solid bar represents the full length of the rNV96-908 capsid protein. Numbers besides the bar show nucleotide numbers of NV96-908 capsid. Numbers above the bar indicate the planned position of the fragment edges not the actual positions. Small open boxes with numbers indicate each fragment. The N-terminal fragment consists of fragments 1–7 and the C-terminal fragment consists of fragments 8–17. These fragments were constructed using restriction enzyme sites in primers for ligation convenience (Table 2).
