IFNAR1
Anifrolumab (67.7 nM; 20 min) induces sustained reduction of surface IFNAR1 and abrogates STAT1 phosphorylation[2].
Anifrolumab (1 and 10 μg/mL; 6 or 7 d) suppresses differentiation of B cells into plasma cells[2].
Anifrolumab inhibits type I IFN-induced ISRE signaling, with IC50s ranging from 0.004 to 0.3 nM for the IFN-α subtypes, and 0.03 nM and 0.07 nM for IFN-β and IFN-ω, respectively[2].
Anifrolumab (67.7 nM) dose-dependently inhibits IFN-α production from pDCs in response to CpG-A or DNA-IC stimulation, inhibiting 87-95% of IFN-α production[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Immobilized IFNAR1 Protein, Human (HEK293, His, HY-P70483) can bind Anifrolumab. The EC50 for this effect is 21.2 ng/mL. -
Flow cytometric analysis of 1.5X106 U937 cells with Anifrolumab (HY-P99168, red). Cells were fixed with 4% paraformaldehyde. Then 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.
