Abstract
Sheeppox virus (SPPV) and goatpox virus (GTPV) are two pathogens of host specificity. Previous studies have hypothesized that ankyrin (ANK) family may play an important role in determining host range of SPPV and GTPV. In order to verify the function of ANK proteins, it is critical to generate and purify the ANK gene deleted GTPV. In this study, the GFP gene as a reporter gene was connected with two homologous arms of ANK gene by fusion PCR. The ANK gene deleted transfer vectors were generated by inserting the PCR products into PET42b, and were transfected into testicular primary cells which were infected by GTPV. The rGTPV were identified as green fluorescence positive and properly purified. The results showed that GFP gene and two homologous arms of ANK gene were connected. The sequence was inserted in PET42b to form ANK deleted transfer vector. ANK deleted rGTPV was generated successfully by transferring vector and GTPV in cells. The ANK deleted rGTPV was purified and identified in this study. The study successfully generated the ANK deleted rGTPV. It overcomes the technical barrier for future studies about the function of ANK genes.
