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.
