Active Recombinant Human IL21 protein, Fc-tagged

• Cat.No.: IL21-1584H
• Product Overview: Recombinant Human IL21 protein(Gln30-Ser162), fused with Fc tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: 30-162 a.a.
• Form: Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 150 mM NaCl, pH7.5.
• Bio-activity: Immobilized Human IL-21 R, His Tag at 2 μg/mL (100 μL/well) can bind Human IL-21, Fc Tag with a linear range of 0.2-8 ng/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminus.The protein has a calculated MW of 41.9 kDa. The protein migrates as 45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: Gln30-Ser162
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >95% as determined by SDS-PAGE.
• 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.
