Total level of API-5 protein in (A) human carcinoma biopsies and (B) EpCAM-purified cells. (A) Fresh tumor tissues (T) with healthy autologous tissue removed alongside the tumor used as a control (C) of selected biopsies (numbered as in Table I). (B) Tumor tissue (T) or appropriate control (C) from total sample or EpCAM-positive (+)/negative (-) cells (patient nos. 48-50 in Table I). β-actin was used as the loading control and cytokeratin 18 (CK18) was used as the EpCAM (epithelial cell) purification control.
