Recombinant Antibody
Specificity
This antibody binds modified forms of human cytokeratin 8 and cytokeratin 18. It is reported that this antibody recognizes an intracellularly located cytokeratin protein that is strongly expressed in adenocarcinomas.
Alternative Names

Immunogen
The original antibody was generated by fusing the human lymphoblastoid cell line WI-L2-729- HF2 with lymphocytes obtained from mesenteric lymph nodes from a colon cancer patient.
Application Notes
This antibody reacted with a panel of colon cancer cell lines and melanoma cell lines in a immunocytochemical assay. This antibody strongly reacted with antigens expressed on autologous and allogeneic colorectal cancers in an immunohistochemical analysis of formalin-fixed paraffin-embedded tissues (PMID: 3699931). Electron microscopy of colonic adenocarcinoma cells, intact tumor and colonic epithelium by the immunogold technique demonstrated that the C-OU1 antibody reacted with a molecule associated with areas of disruption of the intermediate filaments in the cytoplasm of the tumor cells (PMID: 1607210). This binding of this antibody to different recombinant heterotypic K8/K18 complexes was determined by ELISA. This antibody cannot bind K8(1-65)/intact K18 and intact K8(1-85)/intact K18 complexes in an ELISA (US20050048070).
