The virus was purified by ultracentrifuge . according to the ns gene sequence published by genbank , one primer t - 1 was designed to amplify the cdna by reverse transcript . the other primers nsl - u / ns1 - 1 and ns2 - u / ns2 - 1 . hns2 - u were designed to amplify the ns1 , ns2 and hns2 gene 本實驗用接種雞胚的病毒增殖方法獲得了a / chicken / mudanjiang / 0823 / 00 ( h9n2 )分離株的大量增殖,增殖病毒經差速離心進行純化,經超迷離心濃縮。

One of the branches of nymu instrumentation center is located in the same building ; ultracentrifuges , scintillation counters , and a phosphoimager are free to use ,可供一般生化分子及細胞生物實驗所需。此外,大樓內有陽明大學儀器中心的
