The [Centocor.sup.R] CA 72-4[TM} assay (Fujirebio Diagnostics, Inc./Centocor, Inc.) is a solid phase radioimmunoassay (CA 72-4) (RIA) based on two monoclonal antibodies, cc49 and B72.3, which react with distinct antigenic determinants on a tumor associated glycoprotein TAG 72.

Focusing on the epitope information, using N protein-specific mAbs we thoroughly mapped the antigenic determinants distributed on the SARS-CoV N protein.
Despite the extensive use of PSA as a clinical marker of prostate cancer, much is yet to be learned about the antigenic determinants on the PSA molecule (15).
Cross-reactivity experiments indicated that the amino acid sequence -Xaa-Pro-Thr-COON (where Xaa is a basic amino acid) at B28-B30 is the antigenic determinant. First, modifications to this region produced the greatest disruption in antigenicity (Table 1), and native human insulin displays cross-reactivity.
