The clinical utility of mass spectrometry-based protein markers for managing gastric cancers rests on the robustness of the marker panels. Here, you can explore four distinct protein panels tailored for various clinical applications. The Protein Biomarker Matrix for Gastric Cancer (PBMGC) offers detailed insights into the reliability of each protein biomarker in GCPDB. Users have the option to download the entire PBMGC to customize their own panel or select any pre-defined panel that suits their specific needs.
