下游

N the third quarter, costs were still rising at annual rates of 19 per cent in the upstream industry – oil and gas production – and 12 per cent in the downstream refining industry, the IHS CERA index said.

HS CERA指数显示，去年第三季度，上游工业的成本仍在以19%的年率增长，而下游炼制工业则在以12%的速度增长。

In this study, the DNA fragments coding for amino acids 133～158 of VP1and 20～34 of VP4protein of type Asial FMDV were chemically synthesized and ligated into a tandem repeat 133～158-20～34-133～158. The sequences of signal peptide of Igκ chain and Kozak were fused to the 5'end of this tandem sequence and synthetic oligodeoxynucleotide containing CpG-ISS was fused to downstream of terminal coden of this tandem sequence. And then this long fragment was cloned into the eukaryotic expression plasmid pHook-2, forming a new secreted expression plasmid, named pAS1-E.

在第二章证明了亚洲Ⅰ型口蹄疫病毒VP1蛋白中133～158位氨基酸残基确是一重要B细胞中和抗原表位的基础上，依据第一章获得的口蹄疫病毒亚洲Ⅰ型VP1 cDNA序列及已报道Asial VP4序列，采用真核偏爱密码子化学合成了VP1中编码133～158位氨基酸及VP4中编码20～34位氨基酸这两个抗原表位基因，将其组成133～158-20～34-133～158串联结构，在其5′端加上鼠Igκ链信号肽序列，在翻译调节区加上增强表达的Kozak序列，同时在133～158-20～34-133～158串联结构3'端终止密码子下游加上CpG免疫刺激序列，将这些片段连接后，克隆到真核表达载体pHook-2上，构建成功了DNA疫苗重组表达载体pAS1-E。
