Abstract/OtherAbstract:
|
A novel recombinant bacmid, bEasyBac, that enables the easy and fast generation of pure recombinant baculovirus without any purification step was constructed. In bEasyBac, attR recombination sites were introduced to facilitate the generation of a recombinant viral genome by in vitro transposition. Moreover, the extracellular RNase gene from Bacillus amyloliquefaciens, barnase, was expressed under the control of the Cotesia plutellae bracovirus early promoter to negatively select against the non-recombinant background. The bEasyBac bacmid could only replicate in host insect cells when the barnase gene was replaced with the gene of interest by in vitro transposition. When bEasyBac was transposed with pDualBac-EGFP, the resulting recombinant virus, AcEasy-EGFP, showed comparable levels of EGFP expression efficiency to the plaque-purified recombinant virus AcEGFP, which was constructed using the bAcGOZA system. In addition, no non-recombinant backgrounds were detected in unpurified AcEasy-EGFP stocks. Based on these results, a high-throughput system for the generation of multiple recombinant viruses at a time was established. |
