Figure 1From: Nanobodies targeting conserved epitopes on the major outer membrane protein of Campylobacter as potential tools for control of Campylobacter colonization Amino acid sequence alignment of anti- Campylobacter nanobodies selected for their broad specificity. The structural framework regions are indicated by FR1–FR4 and the red boxes specify the CDRs. On the basis of the variation of the amino acid sequence of the CDR3, the nanobodies were divided in twelve unique groups.Back to article page
