摘要: 提取生长状态良好的MDCC-MSB1细胞的mRNA,以5'端标记有生物素的Oligo dT primer为引物反转录,合成双链后连接Adapter。分级纯化后,通过BP重组反应构建入门文库,滴度为1×105 CFU/mL,文库总容量为1.1×106 CFU,平均插入片段长度为1190 bp,阳性重组率为100%。入门文库扩增后提取质粒,通过LR重组反应转化为表达文库,平均滴度为1×105 CFU/mL,文库总容量为1.2×106 CFU,平均插入片段长度为1087 bp,重组率为100%。构建的表达文库具有较高的质量,为研究鸡传染性贫血病毒的受体及其细胞嗜性奠定了基础。

Abstract: To construct cDNA expressing library using MDCC-MSB1 cells in a good state, cDNA were synthesized using biotin-conjugated Oligo (dT) primer in the 5'end. The doublestrand cDNA was ligated to adapter and passed the cDNA size fractionation columns. The cDNA entry library was constructed by BP recombination. The library had a high titer of 1?105 CFU/mL, and contained a total clones of 1.1?106 CFU with an average inserts size was about 1190 bp. The constructed cDNA expression library by LR recombination had a titer of 1?105 CFU/mL and contained total clones of 1.2?106 CFU, with an average inserts size of 1087 bp. The cDNA expression libraries would be a valuable resource for identification of cell receptors of CIAV on the MDCC-MSB1 cells and its cellular tropism.
