抗原

Kunming rats were immuned with purified recombinant protein, and all the rats produced relatively supernal antibody.

由此表明，体外表达的重组蛋白保留了天然蛋白所具有的抗原性。

However, so far there no reports whether Hsp60 and hsp70 polymorphisms may change Hsp60 and Hsp70 levels, resulting in have an effect on the susceptivity of CHD.

更多与CHD危险度有关，但hsp基因多态性是否通过改变血浆Hsp抗原、抗体水平进而影响CHD的易感性，迄今未见报道。

Swine pox, which belongs to the pox disease complex, is caused by two antigenically different poxviruses

猪痘属于痘病群，是由两种抗原上不同的痘病毒引起的。

An indirect competitive enzyme-linked immunosorbent assay was established for detecting vitellogenin in the whole body homogenate of male swordtail fish.This technique was developed with antiserum of lipovitellinresistance as antibody and Vtg as antigen.

以卵黄脂磷蛋白(lipovitellin，Lv)抗血清为抗体，以纯化的卵黄蛋白原(vitellogenin，Vtg)为抗原，建立了间接酶联免疫吸附反应方法检测剑尾鱼雄鱼整体匀浆液中ρ。

Methods:Using cell culture and immunohistochemical techniques,the peripheral blood specimens from 33 RA patients were designed to test the human T cell lymphotropic virus type Ⅰ related antigens,reverse transcriptase and spontaneous syncytium formation.

采用细胞培养、免疫组织化学技术等对33例RA患者的外周血样本进行人类嗜T淋巴细胞病毒Ⅰ型相关抗原、逆转录酶活性测定及观察自发性合胞体形成。

Since 1997, the goose flocks in some regions of South and East China have experienced severe outbreaks of Newcastle disease virus infection. The results of the in vitro tests indicate that the goose isolates have stronger ability to induce syncytium formation, when compared to chicken and pigeon isolates.

1997年以来我国华南和华东部分地区发生了由新城疫病毒(Newcastle disease virus， NDV)导致的鹅的临诊疾病，而且发现鹅源NDV在体外具有比鸡源和鸽源毒株更强的致细胞融合的能力，这表明NDV的抗原可能发生了变异。

Results PFs did not suppress HIV-1-mediated syncytium formation,however,they significantly increased the viabilities of HIV-1-infected cells and the inhibition rates of p24 antigen levels.Moreover,their effects arrived at the highest in the first trimester,and decreased along with the progress of pregnancy.

结果：各孕期PF并不能抑制MT2和H9/HIV-1 ⅢB细胞的融合，但可以增加HIV-1感染细胞的存活率及减少HIV-1 p24抗原的表达，且效应以早孕期PF最大，中孕期PF其次，晚孕期PF最小，并与剂量呈正相关。

AIM: To isolate bioactive secondary metabolites from the fruits of Schisandra rebriflora Rehd. et. Wils and study their effects on HIV-1 infectivity. METHODS: Inhibition of syncytia formation, HIV-1 reverse transcriptase and protease, protection of HIV-1 infected cells, level of HIV-1 p24 antigen,blockage of fusion were detected. RESULTS: A lignan compound, named rubrifloralignan A, was first isolated as a natural product with modest inhibition effects on syncytium formation and HIV- 1 replication and could protect HIV-1 infected cells with weak inhibition effects on fusion and RT, but it showed no effects on the replication of HIV-1 chronic H9 and PR. CONCLUSION: Rubrifloralignan A is an efficient anti-HIV-1 product with effect on early stage of HIV-1 replication.

目的：从红花五味子果实中寻找活性代谢产物，研究其抗HIV—1活性和作用机制方法：通过合胞体抑制、HIV-1感染细胞保护、HIV—1p24抗原测定、融合阻断、逆转录酶和蛋白酶活性分析等实验，检测分离化合物的抗HIV—1活性并探讨其作用机制一结果：红花五味子甲素能够抑制病毒诱导的合胞体形成，保护病毒感染细胞，抑制病毒在细胞内的复制对HIV-1感染细胞与正常CD4^＋细胞间的融合，逆转录酶活性有一定的抑制作用但是红花五味子甲素不抑制病毒在慢性感染细胞中的复制，也不抑制蛋白酶的活性、结论：首次从天然产物中分离得到红花五味子甲素，它对HIV—1病毒复制早期具有抑制作用

Similar expression of HCV core antigen on serial passages suggested that the complementation system of TMV-based vectors was stable in systemic infection and expression.

通过连续三次传代，这个系统都具有系统侵染的特性，且稳定地表达核心抗原。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
