  • Construction and Identification of Recombinant Adenovirus Vector of Rat Galectin-9 Gene

    ObjectiveTo clone full-length cDNA of rat galectin-9 and construct recombinant adenovirus granule containing rat galectin-9 gene. MethodsThe galectin-9 gene was amplified by RT-PCR from rat liver tissue and inserted orientationally into plasmid pDC316-GFP digested by restriction endonucleases NotⅠ and HindⅢ. The recombinant pDC316-GFP-galectin-9 shuttle plasmid was identified by PCR, restriction endonuclease digestion and sequencing, and then co-transfected with rescue plasmid pBHGlox△E1.3Cre into HEK-293 cells by liposome reagent. Recombinant adenovirus vector containing rat galectin-9 gene (Ad5-galectin-9) was generated by sitespecific recombination and confirmed by PCR, and then Ad5-galectin-9 was propagated in HEK-293 cells and purified. The infectious titer of viral stock was determined by TCID50 assay. ResultsConstruction of pDC316-GFP-galectin-9 shuttle plasmid was confirmed to be correct by PCR, restriction endonuclease digestion and sequencing. Construction of recombinant adenovirus Ad5-galectin-9 was confirmed to be correct by PCR. The infective titer of Ad5-galectin-9 was 1.4×109 U/ml. ConclusionRecombinant adenovirus vector containing rat galectin-9 gene (Ad5-galectin-9) is successfully constructed, which provides the foundation of further research on the function of galectin-9 gene.
