Development of a Serum Biomarker Assay That Differentiates Tumor-Associated MUC5AC (NPC-1C ANTIGEN) from Normal MUC5AC

<table>NPC-1C antigen detection in colorectal cancer patient serum. The NPC-1C antigen sandwich ELISA was used to test control serum pooled from normal donors (AB serum, shown in open circles with a thick connecting line), in comparison with serum from five individuals diagnosed with colorectal cancer (shown in various symbols and colors). Serum specimens were tested at the dilutions indicated on the <i>x</i>-axis.</table>
