Electrophoresis mobility shift assay(EMSA)showed that both NPs of Z10 and Z37 hantaviruses bound specifically to the double-stranded DNA probe possessing the 18-nucleotide inverted repeat sequences in vitro.

• 然后将该探针与纯化的Z10、Z37株的核蛋白NP进行非变性凝胶电泳迁移改变实验(EMSA)后发现,重组的Z10、Z37株的核蛋白NP,在体外均可特异地结合其基因组末端反向重复序列形成的双链探针。
