KREX™-based protein array for high-throughput quantification of autoantibodies to Cancer-Testis (CT) antigens. CT antigens are a group of unrelated proteins that show highly restricted expression profiles in adult somatic tissues but which are aberrantly expressed in various cancers.

Key applications:

1. Unique differential profiling of cancer-antigen in various cancer types
2. Patient stratification in checkpoint inhibitor studies
3. Determination of epitope recognition in patients or monitor patients in experimental cancer vaccine studies
