Detection of gastric carcinoma-associated antigen MG7-Ag in human sera using surface plasmon resonance sensor.

BACKGROUND MG7-Ag is a kind of gastric cancer-specific tumor-associated antigen and has been investigated to serve as a marker of gastric cancer for early diagnosis. METHODS Surface plasmon resonance (SPR) sensor was used for the detection of MG7-Ag in the sera of gastric cancer patients to develop an innovative, simple and rapid assay method for early… CONTINUE READING
