Antibodies against tumor markers used for the different tumor histologies were a cocktail of: EpCAM, pan-cytokeratin (pan-CK) and CK19 for prostate cancer (GU) and triple-negative breast cancer (TNBC)7; EpCAM, pan-CK, CK19, asialoglycoprotein receptor 1 (ASGR1) and Glypican 3 (GPC3) for hepatocellular carcinoma (HCC)26; and Sox10, melanocyte differentiation antigen (Melan-A) and neuron glial antigen-2 (NG2) for uveal melanoma (UM)27. Here, KRT19 is linked to hepatocellular carcinoma.
