Avian leucosis virus ; monoclonal antibody ; DAS-ELISA

禽白血病病毒；单抗；双抗体夹心法ELISA

A double-antibody sandwich ELISAemploying monoclonal antibody 5G5 was developed for detection of P27 antigen of avian leucosis virus.The limit of viral antigens detected was 5?

利用原核表达的禽白血病病毒P27蛋白作为抗原制备的单抗作为包被抗体，以制的酶标兔抗P27作为酶标抗体，在国内首次建立了检测ALV抗原的双抗体夹心ELISA方法。

The recombinant RSV vaccinia virus VMS11G75F was constructed strictly according to the rules of biological products and all tests for contamination by bacteria, Chicken leucosis virus and mycoplasma gave negative results, so that vaccinia recombinant VMS11G75F could be a candidate of recombinant RSV live vaccine for human test.

HSV重组痘苗病毒VMS11G75F是严格按照人用疫苗株程序构建而成，并对多种外源因子污染(包括：细菌、鸡白血病病毒、支原体等)进行了检查，均为阴性，因此是一株可供人体实验观察的RSV基因工程活疫苗候选株。

To explore the influence of reticuloendotheliosis virus and subgroup J avian leucosis virus infection on chicken cellular immunity,the mitogenic response to ConA of blood and spleen lymphocytes tested and analyzed with 3H-thymidine(3H-TdR) incorporation assay at different intervals after infection or co-infection of single or both viruses.

自1974年分离出网状内皮增生症病毒[1]和1991年分离出禽白血病病毒J亚群[2]以来，在我国先后分离出不同毒株的REV和ALV-J，并开展了病原学、流行病学、致病性和免疫反应以及预防诊断等方面的研究，揭示出不同的致病性，并且确认它们都可造成感染鸡群免疫抑制，成为一些

In order to discuss the interaction of viremia and antibody caused by reticuloendotheliosis and avian leucosis virus of subgroup J, REV, ALV-J and REV+ALV-J were injected to SPF chicken at 2 d separately, then tested the viremia and antibody dynamically for 7 weeks. The results indicated that compared with single infection, the dynamic viremia level of REV and ALV-J wasn't obviously different when coinfected.

为了研究禽网状内皮增生病病毒、禽J亚群白血病病毒共感染时对彼此病毒血症及抗体反应的影响，2日龄SPF鸡分别接种REV、ALV-J或同时2种病毒造成共感染，对各感染组7周内的病毒血症及抗体反应进行动态检测。

Is the most effective way for leukaemia patients to recover.

是白血病人得以痊愈的最有效的方法。

Recently,one of my friends had received the test of leukaemia.

我的一个好朋友最近接受了白血病测试。

One of my good friends have recently been tested for leukaemia.

我的一个好朋友最近接受了白血病测试。

Nine years later, when I returned to look for him, he was dead from leukaemia.

九年后，当我回到寻找他时，他已经死了白血病。

Leukaemia is one of the most common malignant tumors in children.

白血病是儿童最常见的恶性肿瘤。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
