CA125/MUC16 is a serum marker that is used routinely in gynecologic practice to monitor patients with ovarian cancer. It is a mullerian duct differentiation antigen that is over expressed in epithelial ovarian cancer cells and secreted into the blood, although its expression is not entirely confined to ovarian cancer. Most biochemical studies have concluded that MUC16 is a high molecular mass glycoprotein, although estimates of its size range from 200 to 2000kD with smaller 'subunits' being described by some investigators.
Applications:
Suitable for use in ELISA, Flow Cytometry, Western Blot and Immunohistochemistry. Other applications not tested.
Recommended Dilutions:
Western Blot: 1-5ug/ml after electrophoresing 20ug of sample.
Immunohistochemistry: 1-5ug/ml
Note: Dilute in PBS or medium which is identical to that used in the assay system.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
