    Abstract:
    Xanthine Oxidoreductase (XOR) is the key enzyme in purine metabolism and also produces oxygen free radicals. As a continuation of our previous work, in this study, we constructed a retrovirus expression vector (pLNCX2-XOR) containing full length of XOR cDNA. Retrovirus was produced by the virus package cell line PT-67 following the transfection of PT-67 with pLNCX2-XOR and used to infect the human primitive neuroectodermal tumor cell line (PFSK). Infected PFSK cells were selected by G418 to establish cell line with stable expression of XOR. The expression of XOR in the cell line we established was confirmed by RT-PCR, Immunocytochemistry and XOR activity assay.
