Firstly, the eo genes of csfv - jl and csfv - ln9912 strains were amplified by rt - pcr and nested pcr and then sequenced after cloned into t easy vector. comparing the eo sequences with other strains eo by biosoftwares, dnastar5. 0 and bioedit, the phylogenetic analyse revealed that all of the strains we have sequenced could be divided into groupl and groupii. two amino acid streches of 15 csfv strains eo, which form the rnase active site, and histidine residues essential for rnase catalysis in both ones were highly conserved. the eo protein propertys of antigen epitope, hydrophobicity, isoelectric point were also predicted by bioinformatic method
首先，採用rt - pcr和nest - pcr技術擴增了csfv - jl株和csfv - ln9912株eo基因，插入teasy載體后測序，應用dnastar5 . 0和bioedit軟體將其與本實驗室已測其它毒株和genebank中登錄的csfv代表毒株eo基因序列進行比較，繪制了遺傳進化樹並預測了eo蛋白的抗原表位、疏水性、等電點等特性。
