謹慎地，就像每一次進入一座房子他自己的或並非他自己的的時候那樣，小心翼翼地，因為床墊子那蛇狀螺旋彈簧已經陳舊了，黃銅環和蝰蛇狀拱形擋頭也鬆鬆垮垮的，一用力過頭就顫悠顧慮周到地，就好像進入肉慾或毒蛇的巢穴或隱身之處似的輕輕地，省得驚動她虔誠地，因為那是妊娠與分娩之床，合巹與失貞之床，睡眠與死亡之床。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 ）的原核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，結合大腸桿菌蛋白質合成體系對氨基酸密碼子使用的偏愛性，設計了echistatin編碼基因，體外人工合成編碼基因dna片段，通過適當的限制性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。
