Specification

• Source: HEK293
• Species: Cynomolgus
• Tag: Fc
• Form: Lyophilized from 0.22 μm filtered solution in 51 mM Tris,100 mM Glycine,25 mM Arginine,150 mM NaCl,pH7.5 with trehalose as protectant.
• Bio-activity: Immobilized Cynomolgus IL-21, His Tag at 5 μg/mL (100 μL/well) can bind Cynomolgus IL-21 R, Fc Tag with a linear range of 1-20 ng/mL.
• Molecular Mass: This protein carries a human IgG1 Fc tag at the C-terminusThe protein has a calculated MW of 51.0 kDa. The protein migrates as 60-67 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Proteinlength: Cys20-Glu232
• 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.
• Protein length: 20-232 a.a.
