Abstract:
This study was aimed to construct a lentiviral vector of ha1 gene and obtain a stable packaging cell lines, which will be beneficial to guiding further study on the foundation of ha1 on the dissociation of graft versus host disease (GVHD) and graft versus leukemia (GVL) effect after allogenic hematopoietic stem cell transplantation (allo-HSCT). The targeting ha1 gene was obtained from plasmid T-ha1 by digesting. Then the ha1 gene was subcloned into the lentiviral vector pRRLSIN, cPPT, PGK/GFP, WPRE to construct a lentiviral vector carrying ha1 gene named pLenti-ha1 plasmid. And the pLenti-ha1 plasmid was confirmed by PCR, digesting and sequencing. 293T cells were co-transfected with lentiviral vector pLenti-ha1 and packaging system. The titer of virus was tested by real-time PCR. The results indicated that the construction of ha1 recombinant lentiviral vector was confirmed to be exact by PCR assay, digesting and sequencing; the assayed titer of virus was 2.0 × 10(8) TU/ml. In conclusion, the lentiviral vector of ha1 gene is constructed successfully.
