Anti-OCI-5 antibodies enable researchers to detect and measure the OCI-5 antigen in biological samples. This target is a reported synonym of the GPC3 gene, which encodes glypican 3. This protein is known to function in the morphogenesis of anatomical structure and the Wnt signaling pathway, among other biological roles. The human version of OCI-5 has a canonical amino acid length of 580 residues and a protein mass of 65.6 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cell membrane of cells. Other names for this target antigen include DGSX, DGSX, and GTR2-2. Western Blot is the most common application for the OCI-5 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
