Figure 3From: Selection, affinity maturation, and characterization of a human scFv antibody against CEA protein Identified scFv antibody sequences. Peptide sequences are reported in single-letter code. Amino acids in the mutated clones identical to parental MA39 are represented by a dash. CP1 ā B18 and E1 ā E16 groups of clones were isolated from first and second maturation libraries, respectively. Letters "q" and "t" correspond to glutamine and tryptophan amino acids in suppressed nonsense codons.Back to article page
