  1. In this paper, first strand cdna of 3abc gene was synthesized using template rna extracted from cells infected with fmdv. the complete 3abc gene about isoobp was amplified by pcr and ligated into pgem - t easy vector. after transforming e. coli dh5 a, ampicillin resistant colonies were isolated and plasmid dna was prepared and analyzed by restriction analysis and pcr. presence of the full length 3abc gene was verified by nucleotide sequence analysis and the plasmid containing the expected sequence was named as pgem - 3abc. comparing the aquired sequence of 3abc with that of reference strains, the homology is more than 99 percent. the pgem - 3abc was digested with sal i and bgl ii and ligated into xho i and bgl ii - digested expression vector ptriex - 4 neo. lt was identified by restriction analysis and pcr and sequencing that this fragment had a 17bp deletion hi the nucleotide sequence 708bp of 3abc gene, which happened to form a terminator codon behind 3ab gene, but it contained the complete open reading frame ( orf ) of 3ab gene. positive clones were selected and induced with lmmol / l isopropyl - d - galactoside ( iptg ), bacteria were detected by sds - page and western blotting after properly treated. the results showed that the 3ab gene expressed successfully in e. coli and 33. 5ku fusion protein can be recognized by the positive bovine serum of fmdv. the amount of target protein is over 26 % of the total bacteria protein by gel thin layer scanning analysis

    擴增產物連接到pgem - teasy載體中,轉化大桿菌dh5菌株,篩選氨芐青霉素抗菌落,提取質粒經酶切鑒定、 pcr分析以及確證測序證明,所克隆的1500bp左右的片段含有完整的3abc基因,與國外參考序列相比,同源在99以上。將重組質粒pgem - 3abc和表達載體ptriex - 4neo分別用sal和bgl與xho和bgl消化后,亞克隆3abc基因至表達載體ptriex - 4neo中,通過酶切鑒定、 pcr擴增以及序列分析,發現克隆到ptriex - 4neo載體上的片段於3abc基因708bp處出現了17bp的缺失,碰巧在3ab基因后形成一終止密碼子,但3ab基因的閱讀框架完整,選出含有3ab基因完整閱讀框架的陽克隆,用iptg誘導表達,收集菌液進行sds - page電泳、 westernblotting分析,果表明, 3ab基因在大桿菌中成功表達,其表達產物為分子量33 . 5ku的融合蛋白,並能被口蹄疫病毒陽血清識別。經薄層掃描分析,表達量占總蛋白量的26以上。
  2. Conclusions : prokaryotic and eukaryocytic expression plasmids of the shortened hepatitis b surface antigen were successfully constracted, and the target proteins expressed by iptg induced in escherichia coli. as well as in eukaryocyte ( hepg2 and cos - 7 ), then their antigenity were detected

    論:截短的乙型肝炎表面抗分子的和真表達』重組質粒成功被構建及分別在人桿菌efl得到誘導表達和存貞細胞ifj表達,並檢測劍其表達產物的抗
  3. Objective : construct high - level expression system of echistatin in e. coli methods : obtain amino - acid sequence of echistatin from genebank database. considering the bias of usage of 61 available aminoacid codons in e. coli, design the coding sequence of echistatin, synthesize the dna sequence chemically, get single copy coding gene and repeated two copy coding gene of echistatin. insert the sequence into expression vector pbv220, and more, we construct fusion expression clone of echistatin with pcr, identify the recombinant vector by dna sequencing

    目的構建蛇毒鋸鱗蝰素( echistatin )的高效表達體系方法由genebank數據庫檢索蛇毒鋸鱗蝰素( echistatin )的氨基酸序列,合大桿菌蛋白質合成體系對氨基酸密碼子使用的偏愛,設計了echistatin編碼基因,體外人工合成編碼基因dna片段,通過適當的限制內切酶位點插入表達載體pbv220 ,分別構建了echistatin的單拷貝表達克隆、雙拷貝串聯表達克隆;進一步通過pcr技術構建echistatin的融合表達基因克隆。
  4. In this study, we designed a pair of primers based on the sequence of the upstream and downstream of chicken il - 2 gene. about 600 bp chicken il - 2 cdna fragment was cloned from cona - stimulated chicken splenocytes by reverse transcription - polymerase chain reaction ( rt - pcr ) and was subcloned into puc18 vector. recombinant clone was demonstrated by restriction enzyme digestion and dna sequencing. next, we construct recombinant plasmid pproex ? t - il - 2. the cdna of chicken il - 2 gene was subcloned into bamh i / hind iii sites of vector. the recombinant plasmid pproex ? t - il - 2 was transformed into e. coli dh5a and the bacteria was induced with iptg. it was demonstrated by sds - page and western blot that a 18kda protein which was equal to chicken il - 2 protein in molecular weight was expressed in e. coli dh5a. the expression level was up to 30 % of the total bacterial proteins. the purified protein was used to prepare the antibody against chicken il - 2 protein

    經酶切鑒定及dna序列測定,該基因為雞il - 2基因,其序列與sundick等報道的完全一致。在此基礎上,我們把雞il - 2基因亞克隆到大桿菌表達載體pproex ~ ( tm ) ht中,構建重組表達質粒並進行確證序列測定,重組質粒測序果表明將編碼雞il - 2成熟蛋白的基因正確地插入到表達載體pproex ~ ( tm ) ht的目的位點。重組質粒轉化受體菌dh5後用iptg於37進行誘導培養, sds - page和westernblot分析顯示,表達的雞il - 2融合蛋白分子量約為18kda ,表達的融合蛋白經薄層掃描發現目的蛋白表達量約占菌體蛋白的30 。
