Monoclonal Mouse Anti-Human
CA 125
Clone M11
Recognizes a mucin-like glycoprotein larger than 200 kDa, expressing the CA 125 epitope.
The antibody labels a variety of tumors, such as some adenocarcinomas of the colon, breast carcinomas, malignant mesothelioma, uterine adenomatoid tumor, lung bronchoalveolar carcinoma, and ovarian endometrioid and serous carcinomas. Antibodies to CA 125 may be useful for the differential diagnosis of adenocarcinomas, as positive reactivity in prostate, colorectal and renal carcinomas is rare (1-3).

Ovarian carcinoma (FFPE) stained with FLEX Anti-CA 125, Code IR701/IS701.
Serous ovarian carcinoma. The majority of the neoplastic cells show a moderate to strong predominantly membranous staining reaction.
Clinical application for IR701/IS701. For identification of serous ovarian carcinoma and mesothelioma.
Disclaimer: Due to variances among color computer monitors, the colors you see on your screen may not be the exact colors of the stain. The image you see should be considered close renditions to the actual stain.
- Optimized staining performance of both high- and low-expression structures
- Crisp and clear staining with no background
- Optimal laboratory efficiency with ready-to-use antibodies on Dako Autostainer Plus
FLEX Monoclonal Mouse Anti-Human CA 125, Clone M11, Ready-to-Use (Dako Autostainer/Autostainer Plus), is intended for use in immunohistochemistry together with Dako Autostainer/Autostainer Plus instruments. This antibody is useful for the identification of serous ovarian carcinoma (1, 2). Antibodies to CA 125 may also be useful for the identification of mesothelioma (3). The clinical interpretation of any staining or its absence should be complemented by morphological studies using proper controls and should be evaluated within the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.
Competition assays have demonstrated that monoclonal antibody clone M11 does not compete with monoclonal antibody clone OC125 for binding to the CA 125 antigen (7).
Clone: M11 (7). Isotype: IgG1, kappa.
