分子别名（Synonym）:IFN-alpha-REC,IFN-R,IFNABR,IFNARB

种属（Species）：Human

表达系统（Expressed Host）：HEK293 Cells

产品状态（Buffer）：Lyophilized from sterile PBS, pH 7.4

分子量（Molecule Mass）：The recombinant human IFNAR2/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 458 amino acids and predicts a molecular mass of 51.8 kDa. As a result of glycosylation, the apparent molecular mass of rh IFNAR2/Fc monomer is approximately 65-75 kDa in SDS-PAGE under reducing conditions.

内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.

生物活性(Activity)：Measured by its ability to inhibit rh IFNβ mediated protection of WISH Human amnion cells infected with vesicular stomatitis virus (VSV) to viral lysis.

表达区间（Protein Construction）：A DNA sequence encoding the extracellular domain of human IFNAR2 isoform a (NP_997468.1) (Ser 2-Lys 243) was fused with the Fc region of human IgG1 at the C-terminus.

存储条件（Storage）： For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.

运输条件： In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
