Fig. 1From: Design of a chimaeric antigen and its use in the detection of IgG antibodies against rubella virusAgarose gel electrophoresis of P6T and its expression vector after double digestion. The target fragment P6T linked to PGEM-T and the expression vector PET-32a (+) were digested with restriction enzymes BamHI and HindIII, and the obtained target fragment was recovered for identification by agron gel electrophoresis. 1: DNA marker, DL2000; 2: P6T plasmid; 3: double restriction enzyme (BamHI, HindIII) digestion product of pET-32a (+)Back to article page
