    DR3 Antibody (D3 2-1-1) is a mouse monoclonal IgG1 antibody that detects DR3 in human samples through applications such as western blotting (WB), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). DR3, also known as Wsl-1, APO-3, TRAMP, and LARD, is a member of the tumor necrosis factor (TNF) receptor superfamily and plays a crucial role in mediating apoptosis and activating the NFκB signaling pathway. DR3 is primarily expressed in thymocytes and lymphocytes, highlighting its importance in immune regulation and response. DR3′s presence in these immune cells suggests involvement in T-cell development and function, making DR3 a significant target for research in immunology and potential therapeutic interventions. The unique structure of DR3, characterized by its death domain, allows interaction with various intracellular signaling molecules, further emphasizing DR3′s role in apoptosis and cellular homeostasis. Anti-DR3 antibody (D3 2-1-1) is an essential tool for researchers investigating the complex mechanisms of immune responses and cell death.
