BI-1808
Based on 1 Customer Validation
BI-1808 is a fully human IgG1 monoclonal antibody targeting human tumor necrosis factor receptor 2 (TNFR2) (KD = 646 pM). BI-1808 inhibits Treg survival by blocking the interaction between TNFR2 and its ligand TNF-α, and via its IgG1 Fc segment binds FcγR to target and deplete intratumoral Tregs (ADCC/ADCP) and induce pro-inflammatory reprogramming of myeloid cells, ultimately activating CD8+ effector T cell-mediated tumor rejection. BI-1808 can produce synergistic antitumor effects with Pembrolizumab (HY-P9902). BI-1808 can be used for research in tumor immunity.

In Vitro
BI-1808 (7 days) exhibits agonistic effects in inducing Treg cell and CD8+ effector T cell expansion in human Naive CD3+ T cells under crosslinking conditions, with EC50 values of 5.44 nM and 9.12 nM, respectively[2].
BI-1808 (4 h) exerts an agonistic effect on NF-κB signaling induction in TNFR2-NF-κB co-expressing HEK-293 cells (co-cultured with FcγR + Jurkat cells)[2].
BI-1808 (50 μM; pretreated overnight followed by 5-day co-culture) reverses Treg-mediated immunosuppression in in vitro-differentiated Tregs (mixed with Naive CD3+ T cells)[2].
BI-1808 (10 μg/mL; 24 h) has a remodeling effect in human primary monocytes, increasing CD16, HLA-DR, and CD86 expression, promoting TNFα secretion, and reducing IL-10 secretion[3].
BI-1808 binds CHO-K1/hTNFR2 cells with an EC50 of 0.22 nM and binds primary Tregs with an EC50 of 0.053 nM[2].
BI-1808 (1 h) blocks the binding of human TNF-α to human TNFR2 in CHO-K1/hTNFR2 cells with an IC50 of 0.37 nM[2].
BI-1808 (1 h) exhibits targeted binding in in vitro activated human primary CD4+ T cells, with an EC50 of 2.6 nM[3].

Flow Cytometry analysis of HepG2 cells with BI-1808 (HY-P991192, red) . Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then cells were stained with the primary antibody at 1/200 dilution for an hour at 4℃. Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa(HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
