SEQUENCE A sequence database reference for this protein does not currently exist. The SEQRES of chain L includes His tags(AAGHHHHHH) on the C-terminus. The SEQRES of chain H includes His tags(SAGHHHHHH) on the C-terminus. The residue numbering of chain H corresponds to Kabat database in which the residue numbers of antibody are defined. The residues in variable region are assigned with non-sequencial number.
