Donor Antibody: mouse
Acceptor Antibody: Human IgG1 | k
Antigen: CD56 (anti-NCAM (cell adhesion molecule)) antigen on human natural killer cells
Laboratory: ImmunoGen, MA; University Bath, UK
Design: Models of mouse and humanised V regions generated by AbM. Analyse FR residues within 5A of a CDR for changes in size, charge, hydrophobicity or potential to form H-bonds that could disturb the CDR conformation.
Frameworks: VH G36005 | VL KV2F
CDRs: All 6 VH and VL, Kabat Definition except that CDR-H2 was 7 residues shorter at the C-terminus.
Backmutations: None
Binding: Binding to SW-2 cells was "indistinguishable" from mouse mAb using competition binding assays and indirect immunofluorescence binding assays (FACScan).
Expression: transient expression in cos cells
Comment: This mAb was also resurfaced.
Clinical Indication: Small cell lung cancer
