Used in immunological research to study T-cell activation and signaling pathways. Facilitates the detection and purification of CD7-expressing cells through techniques like flow cytometry, ELISA, and affinity chromatography. The Fc tag enables easy capture by protein A/G resins and enhances stability in biological assays. Investigated for its role in developing immunotherapies, particularly in targeting T-cell malignancies and modulating immune responses. Supports binding assays to evaluate interactions between CD7 and its ligands or therapeutic antibodies.
