摘要
采用氯化铯平衡密度梯度离心获得较为纯净的病毒粒子后,经过免疫电镜技术(液相免疫电镜法和免疫胶体金标记法)对P1病毒进行了观察鉴定。结果表明,P1病毒呈球形、无囊膜、直径约为25 nm。
The results of porcine circovirus-like agent P1 morphology were reported here. Relatively pure viral particles were obtained by CsCl equilibrium density-gradient centrifugation,and then detected by immune electron microscopy( Both liquid phase immune electron microscopy and immunogold labeling electron microscopy). The results showed that P1 is spherical in shape,non-enveloped and about 25 nm in diameter.
