Characterization of vaccinia VG9/(SST-14)2-HSA. (A) Schematic illustration of VG9/(SST-14)2-HSA construction. Somatostatin fusion protein (SST-14)2-HSA expression cassette was inserted into TK locus of VG9 strain via homologous recombination. In the expression cassette, gpt gene is driven by the promoter P-7.5 K in cis direction while SST14-HSA is driven by the reverse promoter P-se/I. (B) Western blot analysis of the immunogenicity of HSA and somatostatin in different vaccinia VG9/(SST-14)2-HSA recombinants. The blots were cut prior to hybridization with the antibody to control protein of β-actin during blotting.
