Gastric Cancer Marker Detection and Its Kit Development

The gastric cancer diagnosis and treatment specifications clearly point out that tumor markers need to be detected in the process of diagnosis, efficacy evaluation and follow-up. However, there is currently a lack of gastric cancer markers with high sensitivity and specificity, and the detection of markers is limited to a single index analysis, which has many shortcomings such as long analysis time, large reagent consumption, and high detection cost. Therefore, this project will use protein chips to detect new types of gastric cancer patient markers and establish a multi-diagnostic model for early screening of gastric cancer. Finally, monoclonal antibodies will be produced against various high-specific tumor markers and a gastric cancer diagnostic kit will be established.
