Figure 1From: Clostridium perfringens enterotoxin carboxy-terminal fragment is a novel tumor-homing peptide for human ovarian cancer Representative flow cytometry histograms showing claudin-3/4 expression in primary chemotherapy resistant ovarian carcinoma cell lines after labeling with FITC-conjugated CPE peptide. LCL (negative control), Vero cells (positive control), OSPC-ARK-1 (primary OSPC cell line) and CC-ARK-1 (primary clear cell ovarian carcinoma cell line). Both ovarian chemotherapy-resistant tumors demonstrated high level of claudin-3 and claudin-4 expression. Isotype (solid black peak); FITC-conjugated CPE peptide; (black line).Back to article page
