To generate a bait strain Y2 HGold(pGBKT7-UL24/C) using yeast two-hybrid, the bait plasmid of pGBKT7-UL24/C was constructed by one-step cloning with UL24/C gene fragment amplified from genomic DNA of duck enteritis virus(DEV) CHv strain as a template. And after the plasmid being transformed into yeast strain, the bait protein was detected by selfactivating activity, western blot and toxicity assays. The results indicated that the insert fragment in bait plasmid of pGBKT7-UL24/C was 510 bp. Self-activation a...
