Specification

• Species: Cynomolgus
• Source: HEK293
• Tag: His
• Protein Length: Ile 20 - Ser 134
• Form: Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
• Bio-activity: Immobilized Cynomolgus IL-5, His Tag at 5 μg/mL (100 μL/well) can bind Human IL-5 R alpha, Fc Tag with a linear range of 1-31 ng/mL.
• Molecular Mass: The protein has a calculated MW of 15.0 kDa. The protein migrates as 19-23 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
• Endotoxin: Less than 1.0 EU per μg by the LAL method.
• Purity: >90% as determined by SDS-PAGE.
• Storage: For long term storage, the product should be stored at lyophilized state at -20°C or lower.
  Please avoid repeated freeze-thaw cycles.
  This product is stable after storage 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.
