Transcription and expression of HCV core-IFN-α2a recombinant viruses. (A) Identification of pFBD-H1 and pFBD-H2. M: 1Kb Plus DNA ladder; pFBD-H1 and pFBD-H2 samples were digested by BamHI and EcoRI. (B) Identification of pFBD-H3 and pFBD-H4. M: 1Kb Plus DNA ladder; pFBD-H3 and pFBD-H4 samples were digested by BamHI and EcoRI. (C) RT-PCR results of HCV core gene in recombination viruses infect cells. Total RNA was isolated from Sf9 infected with vAcH1, vAcH2, vAcH3, or vAcH4. cDNA was synthesized with SuperScript First Strand Synthesis kit (Invitrogen) with 0.5 to 1.0 μg RNA according to the manufacturer’s instructions. Quantitative RT-PCR reactions were carried out using SYBR Green PCR master mix reagents on an ABI 7500 Fast Real-Time PCR System (Applied Biosystems). (D) Expression of HCV core-IFN-α2a fusion protein in recombinant virus infected cells. M: protein marker. Cells were harvested at 72 h post-infection (hpi) and lysed in SDS-PAGE loading buffer. Twenty micrograms of total protein was separated by SDS-PAGE and subjected to Western blot assay.
