We are setting up an ELISA type of assay for CA125. On your web page: Applications: Uses: Detection of CA125 antigen. Suggested pairs for sandwich immunoassay (capture-detection): NB120-10032 (capture) with NBP2-11624 or NB600-1468 as detection. Can you send me more details how these antibodies have been working in your sandwich immunoassay?

Name: CA125/MUC16 Antibody (X75)
Brand: Novus Biologicals
SKU: NB600-1468

These antibodies have been tested with very general sandwich ELISA, without any assay optimization, just to determine which MAbs work together as pairs. Coat plate with NB120-10032 in alkaline carbonate buffer Post-coat with casein Add HRP-conjugated NBP2-11624 and antigen to plate Incubate microplates for 45 min at room temperature with shaking Wash 5 times with saline-Tween Add 100 ul of substrate Stop enzymatic reaction addition of 5% sulphuric acid. Measure the optical density. The sensitivity without optimization has been around 5 IU/ml. But we really do not have any recommended protocol and the suitability and sensitivity of the Abs should be determined in your own assay.

Background: CA125/MUC16

MUC16 (CA125) 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 2000 kDa with smaller 'subunits' being described by some investigators.
