Chimeric Use Statement:This chimeric human antibody was made using the variable domain sequences of the original Mouse IgG3 format, for improved compatibility with existing reagents, assays and techniques.
Specificity Statement:Lewis Y (Ley) is a blood group antigen expressed at high levels on the surface of epithelial tumors, including small cell lung cancer.
Application Notes:The murine 3S193 showed high specificity for Ley in ELISA tests with synthetic Ley and Ley-containing glycoproteins and glycolipids and also reacted strongly in rosetting assays and cytotoxic tests with Ley-expressing cells (Scott et al, 2000). Murine 3S193 was humanised and in antibody-dependent cell-mediated cytotoxicity assays displayed 100-fold greater activity (Kitamura et al, 1994). 3S193 has been used to screen tumour samples for Ley expression using immunohistochemistry (Krug et al, 2007). A crystal structure of the humanised antibody has been obtained to 1.9 Å resolution (Ramsland et al, 2004).
