A subset of bovine antibodies have an exceptionally long third heavy-chain complementarity determining region (CDR H3) that is highly variable in sequence and includes multiple cysteines. These long CDR H3s (up to 69 residues) fold into a long stalk atop which sits a knob domain that is located far from the antibody surface ...
