| Bioactivity | Teplizumab (MGA-031) is a Fc receptor non-binding anti-human CD3 monoclonal antibody. Teplizumab reduces the loss of beta-cell function. Teplizumab can be used in the research of type 1 diabetes[1][2]. |
| Target | CD3 |
| Invitro | Teplizumab (10 ng/mL-10 μg/mL, 5 days) induces human CD8+ T-cell proliferation[3]. Teplizumab (6 days) increases the expression of CD25 and intracellular CTLA4 on CD8+ cells (freshly isolated PBMCs)[3]. Cell Proliferation Assay[1] Cell Line: |
| In Vivo | Teplizumab (0.24 mg/kg, i.p.) induces migration of human CD4 T cells to the lamina propria and ablated the treatment effects of the drug on graft survival in NSG mice[2]. Animal Model: |
| Name | Teplizumab |
| CAS | 876387-05-2 |
| Appearance | Liquid |
