It s good method to authenticate staphylococci coagulase test by the slidex staphkit method and the tube method with highly sensitivity and specificity .

乳胶血凝法和试管法敏感性和特异性较高，是鉴定葡萄球菌凝固酶试验的好方法，玻片法的特异性较差，可能是由于人血浆中产生的葡萄球菌抗体所致。

It's good method to authenticate staphylococci coagulase test by the slidex staph?kit method and the tube method with highly sensitivity and specificity .Otherwise ,the specificity of the slide agglutination test method is lower than the others ,perhaps it caused by staphylococci antibody in human plasm.

乳胶血凝法和试管法敏感性和特异性较高，是鉴定葡萄球菌凝固酶试验的好方法，玻片法的特异性较差，可能是由于人血浆中产生的葡萄球菌抗体所致。

The specificity of the antibody A was good, but a cross-reaction with AFB2,AFG1,AFG2, with an exception of AFM1,was found.

以蛋黄抗体A为材料，研究了抗体的特异性，结果表明：该抗体有较好的特异性。

RNA interference represents a common biological phenomenon of double-stranded RNA mediated post-transcriptional gene silencing, which lies in altitude plants and animals. The mechanism of this process is described as that: the dsRNA in cells are cut into double-stranded small interfering RNA. By joining with an effector complex termed RISC (RNA-induced silencing complex), siRNA binds to the cellular RNA with homologous sequences, and contributes to the degradation of the corresponding mRNA, the inhibition of specific gene expression.

RNAi技术是双链RNA(double strand RNA，dsRNA)介导的序列特异性的转录后基因沉默，广泛存在于高等植物和动物中，其机制是细胞内的dsRNA被Dicer剪切成双链的小分子干涉RNA (small interfering RNA，siRNA)与RNA诱导的基因沉默复合物结合，降解与之互补的靶mRNA，特异性抑制靶基因表达。

For developing an immunoassay for multiple residues of pyrethroid pesticides, the hapten N-2- carbanmoyl-(3"-phenoxyphenyl) methyl 3-(2"-Cldoro-3",3",3"-trifluoropropenyl)-2, 2-dimethylcyclopropane- carboxylate was synthesized from cyanohydrin and 3-(2"-Chloro-3",3",3- trifluoropropenyl)-2, 2-dimethylcyclopropanecarboxylic acid via hydrolysis and esterification. The synthesis of the hapten was foundation of preparaing anti- cyhalothrin polyclonal antibodies.

为了制备对单一拟除虫菊酯高特异性的抗体，以菊酸和氰醇为起始原料，通过水解、酯化反应合成了半抗原N-2-氨甲酰-(3-苯氧基苄基)甲基-3-(2-氯-3，3，3-三氟丙烯基)-2，2-二甲基环丙烷羧酸酯，为进一步制备抗三氟氰菊酯的特异性抗体奠定基础。

Third, the prepared McAbs were identified by cytochemistry, specificity and Western-blot.

然后用细胞化学、特异性、Western-blot等方法鉴定制备抗体的免疫反应及特异性。

Results The diagnostic sensitivity of anti-CCP antibody for RA was 52%, and specificity was 94% by this DIB technique.

结果 斑点免疫印迹试验检测抗CCP抗体对RA的诊断敏感性为52%，特异性为94%，并具有较好的方法学稳定性和特异性。

Of them, a number of genes showed differential expression.

从中选择了28个较有意义的基因，利用RT-PCR方法研究了它们的生精细胞阶段特异性和组织特异性表达特征。

It was a new mousegene in GenBank and named as SRG-L(spermatogenesis related gene expressed in the latestages of spermatogenic cells). The sequence of this cDNA has been deposited in GenBankwith the Accession No. AY352586. 2. Analyses of expression characteristics of SRG-L during mouse spermatogenesis.The results of RT-PCR and Northern Blotting indicated that no expression signal of thisgene could be observed in primitive type A spermatogonia and type B spermatogonia. Asignal first appeared in diplotene/pachytene spermatocytes, and was significantlyintensified in round spermatids and elongating spermatids, findly went down to beundetectable in mature spermatozoa.

RT-PCR和Northern Blotting分析表明：该基因在早期A型和B型精原细胞中不表达，从双线期初级精母细胞阶段开始表达并逐渐上调，在粗线期初级精母细胞、圆形精子细胞及长形精子细胞中均检测到高水平的mRNA，但在成熟精子中消失，具有明显的阶段特异性表达特征，并且组织特异性表达分析显示该基因在睾丸组织中的呈高表达。

Hereby, we presumed that the specific binding of CpG-ODN with TLR9 and the trigger of activating signal be likely to occur in acidic endosomes after uptaken by cells, not on cells ectoblast. It suggested that the specific binding of CpG-ODN with TLR9 very possibly needs a specifical exterior condition, an acidic pH.

但令人困惑的是目前一直未能直接观察到TLR9与CpG-ODN的特异性相互作用，而且免疫细胞膜上并不存在CpG-ODN的特异性结合位点。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
