|Acceptor Antibody:||Human IgG1 | k|
|Antigen:||Human Placental Alkaline Phosphatase (PLAP) and testicular PLAP-like alkaline phosphatase but no cross-reactivity to liver or intestinal enzymes|
|Design:||Mouse FR sequence similar to solved structure D1.3 Study all residue differences between mouse and human FRs with reference to structures of D1.3, NEW and REI. Most differences non-important on the Beta-sheet surface or far from CDRs.|
|Frameworks:||VH human NEWM | VL human REI (modified as in Campath-1H.)|
|CDRs:||All 6 from VH and VL, Kabat Definition.|
|Backmutations:||VH S27F S30T as in Campath-1H|
|Binding:||"Affinity (of humanised) ... reduced somewhat compared to H17E2". Dilution curves of mouse and humanised look similar.|
|Expression:||mouse NS0 myeloma cells|
|Comment:||Used to image ovarian cancer indicating in vivo binding. Source sequence supplied by Dr. Mahendra Deonarain.|
