The pcDNA3.1 (+)-cagW, pcDNA3.1 (+) and the digestion product were separated by electrophoresis. Lanes 1 and 2 depict the 7039 and 5428 bp fragments of pcDNA3.1 (+)-cagW and pcDNA3.1 (+), respectively, Lane 3 is BamHI/EcoRV restriction digest on pcDNA3.1 (+)-cagW plasmid, and lane M is 1 Kb DNA ladder (Thermo Fisher Cat No. 10816-015)
