high molecular weight dna 中文意思是什麼
high molecular weight dna
解釋
高分子質量dna-
In this experiment hcv structural gene was amplified by polymerase chain reaction ( pcr ), and was inserted into baculovirus expression vector pfastbacl to construct a recombinant transposing vector pfbl - cee. the plasmid pfb 1 - cee was transformed into dh1 obac competent e. coli cells. high molecular weight dna was prepared from the overnight cultures from the selected e. coli colonies, which was recombinant baculovirus shuttle vector containing hcv structural gene, named bac - cee
本實驗用pcr擴增hcv結構區基因，克隆到桿狀病毒表達載體pfastbacl中，構建成重組轉座載體pfb1 - cee ，轉化dh10bac大腸桿菌感受態細胞，篩選陽性菌落，抽提大分子質粒dna ，獲得含hcv結構區基因的重組桿狀病毒穿梭載體bac - cee ，脂質體介導轉染sf9昆蟲細胞，出現細胞病變后，收集含有重組桿狀病毒顆粒的培養上消，重新感染sf9細胞，收集sf9細胞，進行12 . 5 sds -聚丙烯酰胺凝膠電泳，可見表達的蛋白條帶。 -
Constructed the fusion protein expression vector of echistatin, . and identify it by dna sequencing. the vector can express echistatin fusion protein at a high level, the fusion protein molecular weight is about 16000 da in sds - page analysis, and the fusion protein consists more than 30 % of total protein, the fusion protein has specific antigen - antibody reaction with rabbit anti - echistatin polyclonal antibody. the fusion protein include : hpk5. his + 6tag, and echistatin. echistatin can be released by cnbr cleavage
構建了echistatin融合蛋白表達載體，經dna測序鑒定正確后，溫控誘導表達，獲得了高效表達，表達產物經505一隊ge分析，分子量為16000oa ，符合預計的融合蛋白分子量，表達產物. ll 』菌體總蛋白的30 %以上， westem一blotting結果顯示，該日的蛋白能夠和echistatin多克隆抗體發生特異性抗原抗體反應，表明我們成功構建了eohistatin的高效融合表達克隆。
