EpCAM/TROP1 proteins play key roles in multiple processes as homogeneous interacting molecules that facilitate communication between mucosal epithelial midgut epithelial cells (IECs) and intraepithelial lymphocytes (IELs) to establish immunity against mucosal infections force. EpCAM/TROP1 Protein, Rhesus Macaque (HEK293, His) is the recombinant Rhesus Macaque-derived EpCAM/TROP1 protein, expressed by HEK293 , with C-His labeled tag.
