Figure 2From: Expression and characterization of recombinant VP19c protein and N-terminal from duck enteritis virusSDS-PAGE analysis of recombinant proteins. M, wide molecular weight protein marker; 1, control E. coli cell transformed without the insert; 2, the whole bacterium of pET32a-VP19c; 3, the whole bacterium of pET32a-VP19c(N). All of strains were grown in the presence (+) or in the absence (-) of IPTG.Back to article page
