The two isolates were positive reaction hi polymerase chain reactions with two pair of primers specific for alv - j and gave antigenically strong reaction hi the indirect fluorescence antibody assay ( ifa ) with alv - j specific monoclonal antibody je9 . negatively - stained electron microscopic and immune - electron microscopic observation demonstrated that viral particles of the inner mongolia and shandong isolate of alv - j , respectively designated imc10200 and sdc2000 strain of alv - j , showed characteristic morphology of alv 利用pcr和间接免疫荧光反应进行鉴定,两株j亚群禽白血病病毒可以被两对alv - j特异性引物扩增(特异条带约2 . 2kb和545bp ) ,且在特异性单克隆抗体je9的间接免疫荧光检测中呈现强阳性荧光反应。
In the procedure , carbon nanotubes were oxidized by nitric acid and then neutralized with naoh to create carboxyl surface groups which were used to adsorb ni ( superscript 2 + ) ions , thereafter the adsorbed ni ( superscript 2 + ) ions were chemically reduced into ni nano - particles as a catalytic center for electroless nickel deposition , all these were further confirmed by infrared absorption spectra and electron microscopic observations 碳纳米管经硝酸氧化和碱中和后表面生成羧基,利用羧基吸附镍离子,之后吸附的镍离子被化学还原为镍的纳米微粒并成为化学镀镍的催化活性中心。
