Following the purification of the expressed protein , a elisa was developed to detect reference antisera of h7 , h5 and h9 subtypes . the result indicated that h7 antisera was positive , h5 and h9 antisera were negative 用電洗脫方法純化菌體表達ha1蛋白后,建立了間接elisa方法,并對aivh7 、 h9 、 h5亞型血清進行檢測,結果h7亞型血清呈陽性, h5 、 h9亞型血清呈陰性反應。
Analysis of h9 subtype : ( 1 ) seven out of fourteen h9 strains tested shared similar reaction patterns with dk / hk / y280 / 97 or ck / hk / g9 / 97 virus , while the rest showed almost no inhibition and low reactivity to all reference antisera Hg亞型的分析: ( 1 )抗原性分析表明七株hgnz病毒與w hk yzso 97和n hk gg 97病毒反應相似。而其它病毒株與抗血清不反應或反應的滴度很低。
