Abstract :
The objective of this study was to clone the full length of coding region of Mage-1 and E2 gene of Hog Cholera Virus (HCV) usingthe plasmid pET101/D-TOPO to get the corresponding recombinant plasmid. Samples were obtained from the liver tissue withhepatocellular carcinoma and a pig spleen infected by HCV from Sukoharjo Middle Java. cDNA were amplified by PCR usingGMTOPOF-GMTOPOR for Mage-1 and RS-1-RS-2 for E2 HCV.The purified PCR products were cloned into pET101/D-TOPO asdirect cloning expression vector. The gene target was transformed into E. coli Top10. Analysis of the recombinant plasmid wasundertaken by sequencing and restriction test. The PCR of Mage-1 gene resulted fragments at + 1105bp for first round PCR and at+ 931bp for the second round. The PCR of E2 gene HCV produced fragment at + 1200 bp. The DNA targets were cloned intopET101/D-TOPO from the blunt end PCR product directly. The sequence of full length of coding region of Mage-1 contained 927nucleotides that encoded 309 amino acids residues. The sequence of the full length coding region of E2 gene HCV was encoded by1218 nucleotide. EcoRV enzyme cuts vector pET101/D-TOPO at nucleotide positions at 545 and 4775bp. The result of EcoRVrestriction had band at 4230 and 2450 for pETGM/MAGE1-HCC and 4200 and 2700bp for pETRS/E2-SH. The recombinant plasmidpETGM/MAGE1-HCC and pETRS/E2-SH were obtained from the blunt end PCR product for direct cloning using pET101/D-TOPO.(FMI 2013;49:101-108)
