Figure 1From: High-yield production of functional soluble single-domain antibodies in the cytoplasm of Escherichia coliProtein sequence alignment of investigated single-domain antibodies. The amino acid sequences of sdAbs 7C12 and EG2 were aligned using the EMBOSS Pairwise Alignment Algorithms. The two cysteine residues forming an intradomain disulfide bridge are highlighted in red.Back to article page
