I digested insert (in pJET) and pNIP40b (mycobacteriophage MS6-derived) vector with XbaI; then I transformed the ligation (ratio 1:1 and 1:3) and the linearized vector (control) in Stbl2. After incubation, I observed huge growing in both plates.
How to solve this problem?
Molecular cloning. Complementation strain. Tuberculosis.
