Figure 1From: Production and purification of high molecular weight oligomers of Yersinia pestis F1 capsular antigen released by high cell density culture of recombinant Escherichia coli cells carrying the caf1 operonExpression and release of F1 protein by recombinant E. coli MC1060 (pBRK-F1) during fermentation. Culture growth was followed (A), and SDS-PAGE and Western blot analysis were performed on bacterial cell lysates (B, 0.05 OD600/lane), and culture supernatant (C, 15 μl/lane).Back to article page
