  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，轉化大腸桿菌dh5菌株，篩選氨芐青霉素抗性菌落，提取質粒經酶切鑒定、 pcr分析以及確證性測序證明，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，同源性在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基因至原核表達載體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性克隆，用iptg誘導表達，收集菌液進行sds - page電泳、 westernblotting分析，結果表明， 3ab基因在大腸桿菌中成功表達，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性血清識別。經薄層掃描分析，表達量占總蛋白量的26以上。
  2. Ln our experiment, a lot of regulator sequences inc1uding the 35s promoter with double enhancer e1ements and the terminator nos, the fl sequence and kozak sequence for improving the genetic statement in the level of translation, were appended on the two s ides of the artifically pseudopleuronectes americanus antifreeze protei n gene by a series of process, and the products were linked into pbil21

    本實驗中人工合成了美洲擬鰈抗凍蛋白基因，並在美洲擬鰈抗凍蛋白基因兩側添加了許多調控序列，如具有加倍增強子的35s啟動子和nos終止子，它們可以促進抗凍蛋白基因的轉錄，及可在翻譯水平上提高基因表達的序列和kozak序列，從而構建了抗凍蛋白基因的高效表達盒。
