  1. The monoclonal antibodies ( mab ) specific for the nucleoprotein of prrsv were used to select a phage random heptapeptide library

    採用噬菌體隨機7肽庫對單克隆抗體ge3識別的抗原表位進行了鑒定。
  2. At first, 1. 67 u g per well mcab all was coated on three wells of a plate, and then 1. 5 x 1011 phage virion was diluted and added, after incubating with the target, wash away unbound phage by tbst ( 0. 1 % tween - 20 ), the bound phage was eluted with ph 2. 2 tris - gly buffer and amplified, the specially bound phage was enriched by taking through addition binding / amplification cycles. ln the following cycles, the stringency of panning can be increased by raising the concentration of tbst or decreasing that of mcab all, collecting and titering the washing phage of last time and output phage in each round, the selective ratio and the false positive rate of each round were worked out, the gradually increasing of selective ratio and decreasing of positive rate shows that the panning was effective. after 4 rounds of panning, 11 phage clones were selected after competitive - ellsa, the dna samples of 8 positive clones and 1 negative clone were sequenced and all the foreign peptides inserted was also deduced, a clear consensus binding sequence emerged

    在本實驗中，利用隨機12肽庫對抗豬瘟病毒（ classicalswinefeverviruscsfv ）糖蛋白me2的單抗a11進行表位篩選，經過四輪篩選以後，隨機挑取11個克隆作競爭- elisa檢測，結果表明，所挑11個克隆中，有9個克隆能對me2蛋白和a11反應產生抑制作用，抑制率最高可達64 ； dna測序以後經過dnastar軟體分析，發現它們的核心序列為anwralsl ，該核心序列與豬瘟病毒e2蛋白的28 - 35位氨基酸ttwkeysh具有同源性；夾心- elisa檢測和western - blotting試驗均證明所挑陽性克隆能被a11所識別；人工合成含核心序列的多肽經間接elisa試驗證實，也能被a11識別。
  3. Thus, immunologists have sought smaller molecules with the antigen - recognition capability of antibodies. the variable domains of the heavy ( h ) and light ( l ) chains are sufficient for antigen recognition but the non - covalent complex of the two variable domains ( fv ) is unstable. it is possible to genetically engineer a single - chain fv ( scfv ) with the h chain v region connected to the l chain v region via a 15 amino acid linker composed of serine and glycine amino acid residues

    二、日本血吸蟲單克隆杭獨特型抗體np30的單鏈狐（ scf ）的構建、表達及對balbic小鼠誘導保護性作用研究l 、日本血吸蟲單克隆杭獨特型抗體np0的單鏈抗體歸cfv ）的構建、表達通過pcr方法體外擴增並經測序驗證的重鏈、輕鏈可變區（ vh 、 vl ）基因先後重組入原核表達質粒ptha90相應的位點上，中間通過一連接肽（ gly在er ） 。
  4. At present, in an attempt to stimulate specific antitumor immunity, experimental models and clinical studies are currently evaluating the potent antigen - presenting capacity of dc combined with single or multiple tumor antigen epitopes. however, there are several problems in utilizing pulsing dc with synthetic immunodominant peptides from identified antigens. 1 ) the potential induction of tolerance ; 2 ) the need to determine the patient ' s hla haplotype, the limitation of therapy to patients whose tumors express defined specific tumor antigens in the context of the correct hla phenotype, the unavailability of peptides for all hla haplotypes ; 3 ) the lack of cd4 help cell - related epitopes for most antigens ; and 4 ) the ctl resulting from such protocols have a good in vitro capacity to kill peptide - pulsed target cells but only a modest capacity to kill tumor cells

    但是，學者們發現這一療法存在著如下的缺陷：單一ctl表位抗原肽的應用其抗腫瘤作用弱於多種腫瘤抗原的聯合應用，且有誘導免疫耐受的潛在危險，有時反而會促進腫瘤的生長；事先需對患者的hla單倍型進行鑒定，以確定ctl表位與hla單倍型是否匹配，目前尚缺乏能與所有hla單倍型相匹配的ctl表位，從而限制了這一療法的應用；這一療法所產生的ctl在體外能有效殺傷經腫瘤抗原肽共孵育過的靶細胞，但對腫瘤細胞的殺傷能力較弱：這種l表位抗原肽缺乏cd4汀h細胞相關的表位，因此，不能誘導有效的th細胞免疫應答。
  5. The gene of amoa in ammonia - oxidizing encodes the active - site polypeptide of ammonia monooxygenase which catalyzes the oxidation of ammonia to hydroxylamine. we designed a pair of primers special for the amoa gene by comparing the known amoa gene sequences and used pcr to amplify the amoa gene fragments

    Amoa基因是編碼氨單加氧酶活性多肽位點基因，我們通過引物篩選合成了對氨氧化細菌amoa基因特異結合的引物序列，利用pcr技術對活性污泥中的amoa基因片段進行特異擴增，得到的dna片段大約為490bp 。
  6. In this experiment, to screen the epitope of e2 protein of classical swine fever virus ( csfv ) defined by the monoclonal antibody ( mcab ) all, which had been prepared in previous experiment, the mcab all was raised in mice and followed by purification, the concentration of protein was assayed by using the bca protein assay kit

    本室利用e2基因疫苗制備了多株單抗，為e2的抗原表位研究提供了條件，我們以噬菌體隨機12肽庫分析鑒定了豬瘟病毒e2蛋白的抗原表位，為深入研究豬瘟病毒的抗原結構、制備更有效的診斷試劑和疫苗提供更多理論依據。
  7. Identification of epitope recognized by monoclonal antibody with phage - displayed random peptide library
