EPCAM and head and neck squamous cell carcinoma: Confocal microscopy was used for EpCAM expression analyses upon immunostaining in cultured patient HNSCC resection samples using IRDye800CW-labeled MT201.<h4>Results</h4>Immunostaining with VU1D9 and MT201 revealed a high, consistent, and specific expression of EpCAM on SCC-UADT in vitro.
