Specificity
This antibody binds the G12D mutant form of human KRAS protein. This ras protein binds GDP/GTP and possess intrinsic GTPase activity, that results in conversion of nucleotide guanosine triphosphate (GTP) into guanosine diphosphate (GDP). This protein plays an important role in many signal transduction pathways and regulation of cell proliferation. Somatic KRAS mutations are highly observed in leukemias, colorectal cancer, pancreatic cancer and lung cancer. KRAS mutation is G12D which is estimated to be present in up to 37% pancreatic cancers and over 12% of colorectal cancers.

Immunogen
3S193 (IgG3) was generated in BALB/c mice by immunisation with Ley-expressing cells of the MCF-7 breast carcinoma cell-line.
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).
