摘要
为构建鸡法氏囊组织互补DNA(cDNA)文库,从3周龄鸡法氏囊组织提取总RNA,用偶联oligo(dT)磁珠纯化mRNA,用SMART(Switching methanism at 5′end of RNA transcrip)技术合成cDNA第1链,用LD-PCR方法扩增双链cDNA。经SfiⅠ酶切消化后,用CHROMA SPIN-400柱去除400 bp以下小片段,获得的双链cDNA与同样酶切的pMyr表达载体连接,电转化大肠杆菌获得cDNA文库。初始文库容量为2.8×10~6cfu,重组子比例为100%,插入片段的大小平均为1.2 kb。扩增后文库容量为8×10^(11)cfu·mL^(-1)。所建文库为鸡传染性法氏囊病毒受体基因克隆及功能研究奠定基础。
In order to clone and characterize IBDV receptor gene(s),mRNAs were isolated from the bursa of Fabricius of 3 week-old SPF chicken for construction of cDNA library using SMART technique.The first strand cDNAs were synthesized by reverse transcription using the CDSⅢprimer with Sfi I site introduced and the double-stranded cDNAs were amplified by Long-distance-PCR.After removing small fragments less than 400 bp,the cDNAs were ligated with the pMyr vector in the CytoTrap^(TM) Two-Hybrid System and transformed ...
