The full hBD2 cDNA was inserted into the multi clone site of a eukaryotic expressive plasmid pcDNA3.1/Myc His and located closely at the upstream of two tag gene (myc and 6 Poly histidines ) so as to construct another recombinant eukaryotic expressive vector of hBD 2 gene: rpcDNA3.1/Myc Hi...

将 h BD- 2的全长 c DNA片段插入编码双重报告基因 Myc和 6个多聚组氨酸的真核表达质粒 pc DNA3.1/Myc- His ，构建出 C端带 Myc和 6× His的 rpc DNA3.1/Myc-His /h BD- 2。

Comparison of the coding regions of BH1-BH4 genes showed that BH1 had a lower sequence identity to other previously published B-hordeins than the other three B-hordeins obtained in this study. BH1 was then cloned in a bacterial expression vector based on bacteriophage T7 RNA polymerase. The resulting plasmid produced a 28.15 kDa protein in Escherichia coli. The potential value of B-hordein genes in grain quality improvement of hull-less barley has been discussed.

并且，在4个基因BH1～BH4中，BH1与先前报道的B组醇溶蛋白基因有较低的序列相似性，因此我们对BH1基因进行了原核表达，含该基因的表达载体在大肠杆菌中表达出相对分子质量为28.15 kDa并以包涵体形式存在的蛋白，进一步对其在青稞谷粒品质改良中的潜在价值进行了探讨。

They also found that "CRISPR interference," as this phenomenon is known, involves the targeting of the incoming plasmid or virus DNA directly.

他们也发现了CRISPR干扰作用，正如被认识的一样，该作用包括间接将进入的质粒或者病毒DNA作为目标。
