Interferon alpha/beta receptor 2 (IFNAR2) is also known as IFN-alpha binding protein, IFN-alpha/beta receptor 2, Type I interferon receptor 2, IFNABR and IFNARB, which is a single-pass type I membrane protein and belongs to the type II cytokine receptor family. IFNAR2 can associate with IFNAR1 to form the type I interferon receptor. IFNAR2 is a receptor for interferons alpha and beta.IFNAR2 involves in IFN-mediated STAT1, STAT2 and STAT3 activation. Isoform 1 and isoform 2 of IFNAR2 are directly involved in signal transduction due to their association with the TYR kinase, JAK1. Isoform 3 of IFNAR2 is a potent inhibitor of type I IFN receptor activity.Genetic variations in IFNAR2 influence susceptibility to hepatitis B virus (HBV) infection.

Recombinant Human IFNAR2 /IFNABR Protein,C-Fc Tag (rh IFNAR2 /IFNABR Fc Chimera) Ile 27 - Lys 243 (Accession # NP_997467) was produced in human 293 cells (HEK293) at ACROBiosystems.

Molecular Characterization
rh IFNAR2 /IFNABR Fc Chimera is fused with a human IgG1 Fc tag at the C-terminus, and has a calculated MW of 51.4 kDa. The predicted N-terminus is Ile 27. DTT-reduced Protein migrates as 66-90 kDa in SDS-PAGE due to glycosylation.

Less than 1.0 EU per μg of the rh IFNAR2 /IFNABR Fc Chimera by the LAL method.

>95% as determined by SDS-PAGE.

Lyophilized from 0.22 μm filtered solution in 50 mM tris, 100 mM glycine, pH7.5. Normally Mannitol or Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for reconstitution instructions and specific concentrations.

Avoid repeated freeze-thaw cycles.
No activity loss was observed after storage at:
In lyophilized state for 1 year (4°C); After reconstitution under sterile conditions for 3 months (-70°C).
