A method for constructing a recombinant vector of the Korean isolate SARS coronavirus 2 YS006 (SARS-COV-2/human/KOR/YS006/2020) or a derivative thereof, comprising:
- (1) preparing the four cDNA fragments of SARS coronavirus 2 YS006, each corresponding to the fragment between the restriction sites recognized respectively by restriction enzymes SfoI (677) and PmeI (6748), the fragment between the restriction sites recognized respectively by the restriction enzymes PmeI (6748) and MluI (13956), the fragment between the restriction sites recognized respectively by the restriction enzymes MluI (13956) and BamHI (25314), and the fragment between the restriction sites recognized respectively by the restriction enzymes BamHI (25314) and StuI (29529);
- (2) constructing a BAC vector;
- (3) sequentially inserting the cDNA fragments into the BAC vector;
- and
- (4) inserting a reporter gene into the BAC vector.
