Background

The HE4 gene encodes a protein that is a member of the WFDC domain family. The WFDC domain, or WAP Signature motif, contains eight cysteines forming four disulfide bonds at the core of the protein, and functions as a protease inhibitor in many family members

FAQs for HE4/WFDC2 Protein (NBP3-07109). (Showing 1 - 1 of 1 FAQ).

1. I would like to build a sandwich ELISA for detection of HE4 levels in human blood. I found there are several HE4 antibodies from your company. Could you please provide me some information among these products, which two antibodies will work well with the HE4 antigen in a sandwich ELISA pair?
   • At this time we have not tested any of our HE4 antibodies for use in a Sandwich ELISA. As such, we cannot say with certainty, which will work together as an effective pair. Often times in our experience, choosing a monoclonal antibody for capture, and a polyclonal antibody for detection will yield great results. If you plan on testing any of our HE4 antibodies for use in a Sandwich ELISA then we would encourage you to apply for our Innovators Reward Program. Under the terms of this program, you will be eligible for a full credit in exchange for your data, in the form of an online review, regardless of positive or negative results.
