Development of a Serum Biomarker Assay That Differentiates Tumor-Associated MUC5AC (NPC-1C ANTIGEN) from Normal MUC5AC
Figure 7
Immunohistochemical staining using NPC-1C. NPC-1C staining of normal human pancreatic (a), normal human colorectal (c), pancreatic cancer (b), and colorectal cancer (d). The brown stained areas indicate immunoreactivity of NPC-1C with the cancer-specific MUC5AC antigen. Lung adenocarcinoma stained with a commercially available anti-human MUC5AC antibody (e) or with NPC-1C (f), demonstrating that the NPC-1C antibody does not recognize the lung adenocarcinoma-associated MUC5AC.
