Methods: The NIH 3T3 cells were infected with MCMV containing Tn3-gpt insertion. After incubation the virions were prepared and 230 kb DNA of virus genome was purified from media. DNA sequencing was carried out by DNA cycle sequencing method using 230 kb DNA as template and synthetic oligonucleotide as primer. Results: The pure 230 kb genome DNA was obtained, which can be used as template directly. In the obtained gel picture the bands are clear and intensity, spaces between bands are even and easy to read. It was verified that the Tn3-gpt was inserted in specific site of MCMV genome. Conclusion:It is not necessary to cut large DNA fragment to small fragment in DNA sequencing. We could use 230 kb DNA as template directly.Read More
