Abstract:
Objective To generate a recombinant Adenovh'us encoding a GFP (green fluorescent protein)-report gene and a single-chain trimer of MHC restricted HBsAg CTL epitope. Methods An oligonucleotide encoding H-2Ld restricted HBsAg CTL epitopo was synthesized and fused with H-2Ld DNA molecule to construct the eukaryotic expression vector carrying the HBsAg-SCT gene. The HBsAg-SCT gene was subcloned into a GFP adenovirus expression vector,which was transfeeted into Ad293 cells for packaging and amplification of recombinant adenovirus encoding HBsAg-SCT. Results HBsAg-SCT has been cloned into an adenovirus vector encoding GFP report gene successfully as confirmed by double enzyme digestion and direct sequencing. HBsAg-SCT was expressed by infected Ad293 ceils demonstrated by western blot assay. Conclusion A recombinant adenovirus expressing HBsAg-SCT and green fluorescent protein report gene has been generated.
