Itepekimab can bind IL-33 with high affinity and prevent the binding of ST2 D3 domain to IL-33, thus preventing the formation of IL-33/ST2/IL-1RAcP signaling complex and blocking the production of airway inflammatory mediator[4].
Itepekimab also binds with subnanomolar affinity to different IL-33 cleavage variants, blocks NF-kB signaling in reporter cell lines, and prevents cytokine release from human peripheral blood mononuclear cell[4].

Immobilized IL-33 Protein, Human (His, HY-P70475) can bind Itepekimab. The EC50 for this effect is 157.7 ng/mL. -
Flow cytometric analysis of 1.5×106 HUVEC cells with Itepekimab (HY-P99673, red). 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, cells without incubation with primary antibody were used as the unlabeled control (black).
