blocking antigen 中文意思是什麼
-
Experiment shows that the antigen extracted by autoclave is best for dot - ppa - elisa. applying the x2 test, optimal concentration of antigen was determined, and the optimum dilution of enzyme hrp - spa was 1 : 10. the high specificity of dot - ppa - elisa was proved by the specific blocking test, and also by the cross - reaction test in which the diaphragm does not react with the antibodies against salmonellosis, pasteurellosis, chlamydiosis, hcv, ppv, brucellosis, erysipelas suis, colibacillosis, prv
試驗中對多種方法提取的診斷抗原進行了比較、篩選；確定了dot - ppa - elisa的最佳工作條件；測定了st - 171株的免疫豬血清抗體及c群、 2型人工感染豬血清抗體效價，並初步確定了該方法的陽性標準。 -
The results of antigen substitution and antigen blocking experiments showed the aci - elisa has highly spectific reactivity with csfv. at last, the aci - elisa was used to test 30 samples, it yielded nearly the same results as pcr
最後用aci - elisa與pcr對30份病料的檢測結果比較，表明aci - elisa與pcr檢測結果有很高的符合率。 -
Fortunately, recently widely used bispecific antibody technique provided us a good model for target rca blocking for it ' s dual antigen binding activity and for the availablity of high
為了進一步探討用基因工程的方法制備抗病毒雙特異性抗體的可能性，我們又在現有的條件下構建、表達了 -
Objective the aim of this article was to induce long term survival allografts by blocking cd40 - cd40l pathway with homemade anti - cd40l monoclonal antibody mr1, then purify cd4 + cd25 + regulatory t cells from recipients with long term survival allografts, and adoptively cotransfer such cells together with tcr transgenic allogenic antigen specific cd8 + t cells into immunodeffient mouse. finally study whether cd4 + cd25 + t cells can suppress allogenic antigen specific cd8 + t cell mediated rejection, thus clarified whether cd4 + cd25 + t cell mediated regulation is one of mechanisms of prolongation of allograft survival by cd40 - - cd40l pathway blockade
從移植物長期存活的受體內分選出cd4 + cd25 + t細胞，與tcr轉基因cds + t細胞同時過繼輸注到免疫缺陷小鼠體內，觀察co4 + co25 + t細胞對同種異體反應性cos + t細胞介導排斥反應的作用，探討在阻斷cd40se一~ cd40l共刺激途徑延長移植物存活中， cd4 + cd25 +調節性丁細胞是否是抑制排斥反應的機制之一。
