尿囊的

RNA was extracted from SIV which was purified from infected allantoic fluid, and expected band was observed via RT-PCR. 从纯化的病毒中提取RNA,进行RT-PCR,可扩增出预期的条带。

Harvest allantoic fluid of the further passage in eggs and hemagglutination should not occur. 方法将单价病毒液接种鸡胚尿囊腔,第二代鸡胚尿囊液检查不应出现血凝反应。

Changes of ureide, allantoin, allantoic acid content and al-lantoinase activity in adzuki bean(Vigna angularis)seedlings were investigated. 赤豆种子萌发过程中,幼苗迅速合成酰脲,在酰脲含量达到最大值前,尿囊酸含量高于尿囊素含量,子叶合成酰脲最迅速; 酰脲含量达到最大值后,茎带叶的酰脲含量最高。

Chinese challenge strain F48E8 of newcastle disease virus(NDV) was papagatedin the allantoic cavity of 10-day old embiyonated SPF chicken eggs. 以国内新城疫病毒（Newcastle disease Virus，NDV）标准强毒株F_(48)E_8接种10日龄SPF鸡胚，收集死亡鸡胚尿囊液经蔗糖密度梯度离心后获得较纯的病毒。

The TDA could be cultivated in the allantoic and yolk fluid of embryonated chicken eggs just as primary isolation of other microbial agents. 为了得到大量的病原体纯培养物，我们尝试从鸡胚进行分离。

The mactivated-F48E9, the capsule protein from F48E9 were observed and the allantoic fluid from SPF-chickens was used as a control. 同时，对其灭活毒以及从该毒株提取的囊膜蛋白诱导鸡T淋巴细胞的程序性死亡现象进行了观察，并以健康SPF鸡胚囊液作为对照。
