Crystallization and preliminary X-ray diffraction study of a chimaeric Fab' fragment of antibody binding tumour cells.


Crystals have been obtained of a chimaeric Fab' fragment that binds to a tumour-associated mucin-like glycoprotein TAG72. The Fab' fragment comprises the variable heavy and light-chain domains of a murine monoclonal antibody, B72.3, coupled to human gamma 4 and kappa constant regions. The crystals are orthorhombic and belong to the space group P2(1)2(1)2(1… (More)
