滴度

Methods: The titres of HFRSV in gasmid mite were dynamic observed from cultured cells.

用直接细胞培养动态观察革螨体内HFRSV滴度。

The neutralization antibody titres of pCIL2gD or pCIL6gD were about equal to that of inactivated vaccine group and were higher significantly than that of pcDD group.

在首免和加强免疫后，pCIL2gD或pCIL6gD免疫组的仔猪产生的中和抗体滴度均显著高于pcDD免疫组，达到全病毒灭活疫苗免疫组的抗体水平。

It was shown that the frequency of occurrence and titres of AT1A-AAs increased significantly during the development of hypertension. In the four hypertensive groups studied, the occurrence of AT1A-AAs was most prominent in SHR, 2K1C and neural groups.

实验结果表明，在高血压发病过程中AT1A-AAs的阳性率和滴度均明显增加，在四种模型中，自发性高血压组最明显，2K1C和神经性组次之。

This recombinant adenovirus rAd-poIFN-α could be stably passaged in HEK-293A cells and generated titres in the order of 107 TCID50/mL.

该重组腺病毒于HEK-293A细胞连续传代至20代滴度稳定，为107 TCID50/mL。

The positive rate and geometric mean titres of specific lgg antibodies in patients with ami and omi were significantly higher than those in controls.

急性心肌梗死和陈旧性心肌梗死患者血清肺炎衣原体慢性感染率及其抗体滴度几何均数均明显高于对照组。

Genotype determination in patients co-infected with HCV and HIV should be performed by methods relying on sequence analysis, since serotyping assays have shown a lower sensitivity in co-infected cohorts. HCV-RNA concentration is a strong predictor of response to therapy.

基因型决定了合并感染HIV患者应该接受何种治疗策略依赖于对HCV-RNA的序列分析，只从血清型分析发现对于合并感染患者而言敏感性太低以来，HCV-RNA滴度测定是治疗应答的一个最强预测因子。

Results The maximum titer of recombinant retrovirus with lumbrokinase gene was 1×10^4 CFU/ml.

结果 蚓激酶重组逆转录病毒最高滴度约为1×10^4 CFU/ml。

The BDDcFⅧ gene was ligated behind PUB and 20H1 promotors to create lentiviral vectors pTK161 and pTK162. Meantime lentiviral vectors pTK161' and pTK162' were produced by cloning a green fluorescent protein into pTK151 and pTK152, which was driven by PUB and 2OH1 promotors respectively. Vector supernatant were prepared by using transfer calcium phosphate mediated-cotransfection of 293T cells. The virus vector,△NRF packaging-plasmid, and VSV-G envelope-plasmid was assayed by titers and cFⅧ activity in cell culture supernatant after infection into 293T cells.

用构建携带cFⅧ基因的慢病毒载体pTK161和pTK162（含20HI启动子），同时构建含绿色荧光蛋白的慢病毒载体pTK161'和pTK162'（含2OH1启动子）的方法，分别与包装质粒△NRF、包膜蛋白质粒VSV-G共转染293T包装细胞，将包装好的病毒颗粒再感染293T细胞，检测病毒滴度和培养细胞上清中cFⅧ活性。

Up to now it was the first time that the core-coated biodegradable microspheres containing Interferon α-2a composed of calcium alginate nanoparticles surrounded by the PELA coat was reported.

动物体液免疫检测表明与常规液体疫苗制剂相比，单剂注射PELA乙肝疫苗微球制剂更能有效诱导全身免疫应答，血清中产生的IgG1抗体滴度最高。

Using t-tset to analyze significance of difference. Results: 1. H101 could cause cytopathic effects in U251 cells from 24h and shows greater oncolysis effects when much more H101mRNA expression by enhanced virus tite or prolonged time.

结果： 1。 H101病毒在24小时就可以对体外培养的胶质母细胞瘤U251产生抑制作用，加入的病毒滴度越大抑制率越高，并且随着病毒作用时间的延长，细胞病变反应越发明显，H101mRNA的表达呈上升趋势。2。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
