CD2 Inhibitor

Siplizumab (MEDI-507) is a humanized IgG1 monoclonal antibody against CD2. Siplizumab depletes T cells, decreases T cell activation, inhibites T cell proliferation and enriches naïve and bona fide regulatory T cells.

M3554 is an anti-GD2 antibody-drug conjugate (ADC) based on the humanized anti-GD2 antibody. M3554 consists of the humanized monoclonal antibody hu14.18 (K322A) (HY-P991040) linked to a topoisomerase 1 inhibitor Exatecan (HY-13631) via a cleavable β-glucuronide linker. M3554 can be used for the study of neuroblastoma, osteosarcoma or glioma.

Anti-CD2 Antibody (CB.219) is an anti-human CD2 IgG2b monoclonal antibody. Anti-CD2 Antibody (CB.219) can reduce the infiltration of T cells, macrophages, and the number of Tregs in the colon. Anti-CD2 Antibody (CB.219) can be used for research on infection and inflammation such as toxoplasma infection and colitis. The recommend isotype control of Anti-CD2 Antibody (CB.219): Mouse IgG2b kappa, Isotype Control (HY-P99982).

BTI-322 is a human IgG1κ antibody directed against the CD2 antigen on T cells and NK cells. BTI-322 can block primary and memory alloantigen proliferative responses in vitro. BTI-322 recognizes over 90% of E-rosette-forming peripheral blood lymphocytes and T-cell leukemias. BTI-322 has immunosuppressive activity. BTI-322 effectively inhibits T cell responses in vitro to allogeneic cells. BTI-322 can be used as a T-cell deplting agent. BTI-322 can be studied in research for renal allograft rejection and steroid-refractory acute graft-versus-host disease.
