Tebotelimab
Based on 1 Customer Validation
Tebotelimab (MGD-013) is a humanized IgG4κ bispecific PD-1/LAG-3 dual-affinity re-targeting (DART) antibody. Tebotelimab binds cell-surface expressed PD-1 and LAG-3 with EC50s of 1.65 nM and 0.41 nM in NS0 cells, respectively. Tebotelimab blocks PD-1/PD-L1, PD-1/PD-L2 and LAG-3/HLA (MHC-II) interactions and PD-1 signaling. Tebotelimab restores exhausted T-cell responses and and enhances antitumour immunity.

Flow cytometric analysis of 1×106 Jurkat cells labelling LAG-3 (red) with Tebotelimab (HY-P99573). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa 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 IgG4 kappa Isotype Control (HY-P99003, blue) was used as the isotype control.
