BEVs

Firstly, baculovirus is a key component of insect baculovirus expression system ( BEVS), which is being increasingly used in gene engineering for the research and development of new medicine and vaccines.

首先，杆状病毒是昆虫杆状病毒表达系统的核心部分，该系统已在药物研发、疫苗生产等方面得到广泛应用。

For mass production of hEGF, Bombyx mori baculovirus expression vector system was adopted in this experiment.

为了高效表达人表皮生长因子, 我们采用了家蚕杆状病毒表达系统(Bombyxmoribaculovirusexpressionvectorsystem,BMBEVS).

BEVS is a lytic expression system. There are several proteinase coded by the BmNPV itself.

杆状病毒表达系统是一个裂解性的系统，杆状病毒本身具有多个蛋白酶基因，在表达目的基因产物的同时，这些蛋白酶也得到了表达。

Insect baculovirus expression vector system ( BEVS) is a super high-level eukaryotic expression system developed in 1980s.

杆状病毒表达系统是80年代发展起来的超高效真核表达系统，家蚕杆状病毒表达系统比普通杆状病毒表达系统又具有其多种特有的优势。

But the frequency of recombination was very low ( 0.1%-1%) and it limited further application of the baculovirus expression vector system ( BEVS).

但由于重组病毒产生的比例很低（通常只有01%～1%），成为制约该系统应用的技术瓶颈。

The principal contents of this thesis including: ( 1) expression of the full-length PPAR γ by BEVS.

论文的主要内容包括：（1）利用杆状病毒表达系统表达全长核受体PPARγ。

Expounds principle, technique and development of insect baculovirus expression vector system ( BEVS) that can express foreign gene in a systematic way, which lays a foundation in this field.

综合阐述了昆虫杆状病毒表达载体表达外源基因的原理、技巧和进展，为该领域的进一步研究奠定基础。

The term, which is primarily used in reference to battery electric vehicles ( BEVs), is considered to be one of the major barriers to large scale adoption3 of all-electric cars.

这个词主要用在电动汽车领域，“里程焦虑”也被认为是纯电动汽车被广泛接受面临的主要障碍之一。
