Used in biomedical research to detect and quantify glycosylphosphatidylinositol (GPI)-anchored proteins in human samples. Widely applied in studies related to cell signaling, immune response, and parasitic infections such as malaria, where GPI anchors play a role in pathogenesis. Helps researchers investigate diseases involving abnormal GPI biosynthesis or autoimmune reactions against GPI structures. Commonly used in academic labs, pharmaceutical development, and diagnostic research to assess protein expression and validate experimental models.
