Active Recombinant Human IL2RA protein, Fc-tagged

• Cat.No.: IL2RA-1634H
• Product Overview: Recombinant Human IL2RA protein(Glu22-Cys213), fused with Fc tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 22-213 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5.
• Bio-activity: Immobilized Human IL-2 R alpha Protein, Fc Tag at 2 μg/mL (100 μL/well) can bind Human IL-2, Tag Free with a linear range of 0.4-3 ng/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminus.The protein has a calculated MW of 48.4 kDa. The protein migrates as 60-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: Glu22-Cys213
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.>90% as determined by SEC-MALS.
• Storage: For long term, the product should be stored at lyophilized state at -20°C or lower.Please avoid repeated freeze-thaw cycles. This product is stable after at:
  -20°C to -70°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
