Used in immunological research to study the role of CD24 in cell signaling, immune regulation, and cancer progression. The Fc tag enables easy detection and purification, and supports applications in ELISA, flow cytometry, and protein-protein interaction studies. Frequently employed in therapeutic antibody development and biomarker validation, especially in cancers where CD24 is overexpressed, such as ovarian and breast cancer. Also used to investigate immune checkpoint mechanisms and support drug discovery targeting tumor microenvironment pathways.
