Used in research and therapeutic development for targeting CD98, a protein involved in amino acid transport and cell signaling. Plays a role in modulating immune responses and has been investigated in the context of autoimmune diseases and cancer. Binds specifically to CD98 on cell surfaces, enabling studies on cell proliferation, adhesion, and fusion processes. Also utilized in diagnostic assays to detect CD98 expression in tissue samples, supporting biomarker research and drug development efforts.
