Detection of human TFF3 homodimer in saliva. a Various concentrations of the dimeric TFF3 were measured by the developed sandwich ELISA using TFF-286 as the capture and detector mAbs. A typical calibration curve covering TFF3 concentrations in the range of 0.5–32 ng/ml was obtained. a representative result from one of five experiment is shown. b Salivary TFF3 concentrations were determined by the developed sandwich ELISA. The levels of the salivary TFF3 concentrations in saliva (n = 13) are shown. Eight healthy subjects (closed circle) and five oral squamous cell carcinoma (OSCC) patients (open circle) were indicated. The data was representative of two independent experiments
