Annotated peptide sequences for this antibody are available from its IMGT/mAb-DB record. Peptide sequence search of patented sequences reveals a 100% match between the heavy chain variable domain of margetuximab and SEQ ID NO: 13 from patent US8802093 B2, and antibody clone ch4D5-FcMT3 [2]. Although the patent describes performing Biacore assays to determine antibody-target (ERBB2) affinity, a KD value is not provided.
